Python is a general-purpose, high-level programming language that is widely used for web and application development, data science, and machine learning. It was created by Guido van Rossum in 1991 and takes inspiration from languages like C, Java, Lisp, and Modula-3. Python code is human-readable and has an easy to learn syntax that uses indentation rather than brackets to indicate blocks of code. It supports multiple programming paradigms including object-oriented, imperative, and functional programming.
Python is a widely-used and powerful computer programming language that has helped system administrators manage computer networks and problem solve computer systems for decades. Python has also built some popular applications like BitTorrent, Blender, Calibre, Dropbox, and much more. Going further, the “Pi” in Raspberry Pi stands for Python, so learning Python will instill more confidence when working with Raspberry Pi projects. Python is usually the first programming language people learn primarily because it is easy to learn and provides a solid foundation to learn other computer programming languages. In this webinar,
• Learn what Python is and what it is capable of doing.
• Install Python’s IDE for Windows and work in the Python shell.
• Use calculations, variables, strings, lists, and if statements.
• Discover Python’s built-in functions and understand modules.
• Create simple programs to build on later.

Climate Science Flows: Enabling Petabyte-Scale Climate Analysis with the Eart...Globus
The Earth System Grid Federation (ESGF) is a global network of data servers that archives and distributes the planet’s largest collection of Earth system model output for thousands of climate and environmental scientists worldwide. Many of these petabyte-scale data archives are located in proximity to large high-performance computing (HPC) or cloud computing resources, but the primary workflow for data users consists of transferring data, and applying computations on a different system. As a part of the ESGF 2.0 US project (funded by the United States Department of Energy Office of Science), we developed pre-defined data workflows, which can be run on-demand, capable of applying many data reduction and data analysis to the large ESGF data archives, transferring only the resultant analysis (ex. visualizations, smaller data files). In this talk, we will showcase a few of these workflows, highlighting how Globus Flows can be used for petabyte-scale climate analysis.

Understanding Globus Data Transfers with NetSageGlobus
NetSage is an open privacy-aware network measurement, analysis, and visualization service designed to help end-users visualize and reason about large data transfers. NetSage traditionally has used a combination of passive measurements, including SNMP and flow data, as well as active measurements, mainly perfSONAR, to provide longitudinal network performance data visualization. It has been deployed by dozens of networks world wide, and is supported domestically by the Engagement and Performance Operations Center (EPOC), NSF #2328479. We have recently expanded the NetSage data sources to include logs for Globus data transfers, following the same privacy-preserving approach as for Flow data. Using the logs for the Texas Advanced Computing Center (TACC) as an example, this talk will walk through several different example use cases that NetSage can answer, including: Who is using Globus to share data with my institution, and what kind of performance are they able to achieve? How many transfers has Globus supported for us? Which sites are we sharing the most data with, and how is that changing over time? How is my site using Globus to move data internally, and what kind of performance do we see for those transfers? What percentage of data transfers at my institution used Globus, and how did the overall data transfer performance compare to the Globus users?

How to Position Your Globus Data Portal for Success Ten Good PracticesGlobus
Science gateways allow science and engineering communities to access shared data, software, computing services, and instruments. Science gateways have gained a lot of traction in the last twenty years, as evidenced by projects such as the Science Gateways Community Institute (SGCI) and the Center of Excellence on Science Gateways (SGX3) in the US, The Australian Research Data Commons (ARDC) and its platforms in Australia, and the projects around Virtual Research Environments in Europe. A few mature frameworks have evolved with their different strengths and foci and have been taken up by a larger community such as the Globus Data Portal, Hubzero, Tapis, and Galaxy. However, even when gateways are built on successful frameworks, they continue to face the challenges of ongoing maintenance costs and how to meet the ever-expanding needs of the community they serve with enhanced features. It is not uncommon that gateways with compelling use cases are nonetheless unable to get past the prototype phase and become a full production service, or if they do, they don't survive more than a couple of years. While there is no guaranteed pathway to success, it seems likely that for any gateway there is a need for a strong community and/or solid funding streams to create and sustain its success. With over twenty years of examples to draw from, this presentation goes into detail for ten factors common to successful and enduring gateways that effectively serve as best practices for any new or developing gateway.

and is widely used among the developers’ community.
General Purpose means it can be used for multiple application
such as Data Science, Scripts, Machine Learning, Desktop
Application, Web Application, etc.
High Level Programming Language means human
understandable language (with strong abstraction from the details
of the computer.)
4. What is Python?
Python was developed by Guido van Rossum in the late eighties
and early nineties at the National Research Institute for
Mathematics and Computer Science in the Netherlands.
Why is it called Python?
When Guido van Rossum began implementing Python, was also
reading the published scripts from “Monty Python’s Flying Circus”,
a BBC comedy series from the 1970s. Van Rossum thought he
needed a name that was short, unique, and slightly mysterious, so
he decided to call the language Python.

Python does not support backward compatibility as feature in 3.0
were not available in Python 2.0
6. What is Python?
Python has many reasons for being popular and in demand. A few
of the reasons are mentioned below.
• Emphasis on code readability, shorter codes, ease of
writing.
• Programmers can express logical concepts intarted with
Python fewer lines of code in comparison to languages such
as C++ or Java.
• Python supports multiple programming paradigms, like
object-oriented, imperative and functional programming or
procedural.
• It provides extensive support libraries (Django for web
development, Pandas for data analytics etc.)
• Dynamically typed language(Data type is based on value
assigned)
7. What is Python?
The core philosophy of Python is summarized in the document
The Zen of Python (PEP 20), which includes aphorisms such as:
• Beautiful is better than ugly.
• Explicit is better than implicit.
• Simple is better than complex.
• Complex is better than complicated.
• Readability counts.
https://peps.python.org/pep-0020
8. Reasons to learn Python
1. Simplicity
Python is one of the easiest languages to start your journey. Also,
its simplicity does not limit your functional possibilities.
• Python is a free and open-source language
• Easy-to-learn − Python has few keywords, simple structure,
and a clearly defined syntax. This allows the student to pick up the
language quickly.
• Easy-to-read − Python code is more clearly defined and visible
to the eyes.
• Python is interpreted
• Dynamically typed
9. Reasons to learn Python
1. Simplicity
• Python is interpreted
It has internal compiler. First interpreter will interpret the code if
error any will notify if not it will execute.
• There are no separate compilation and execution steps like C
and C++.
• Directly run the program from the source code.
• Internally, Python converts the source code into an intermediate
form called bytecodes which is then translated into native
language of specific computer to run it.
• No need to worry about linking and loading with libraries, etc.
10. Reasons to learn Python
1. Simplicity
• Dynamically typed
We do not need to specify the type of the variable while
declaration.
It will implicitly decide what type of values is this and thus will
assign the type at the run time.
12. Reasons to learn Python
2. Scalability
Python is a programming language that scales very fast. Among
all available languages, Python is a leader in scaling. That means
that Python has more and more possibilities.
Saying that Python provides the best options for newbies because
there are many ways to decide the same issue.
Even if you have a team of non-Python programmers, who knows
C+ +design patterns, Python will be better for them in terms of
time needed to develop and verify code correctness.
It happens fast because you don`t spend your time to find memory
leaks, work for compilation or segmentation faults.
13. Reasons to learn Python
3. Libraries and Frameworks
Due to its popularity, Python has hundreds of different libraries
and frameworks which is a great addition to your development
process. They save a lot of manual time and can easily replace
the whole solution.
As a geo-scientist, you will find that many of these libraries will be
focused on data visualization, data analytics, Machine Learning,
etc.
14. Reasons to learn Python
4. Huge Community
Python has a powerful community. You might think that it shouldn`t
be one of the main reasons why you need to select Python. But
the truth is vice versa.
If you don`t get support from other specialists, your learning path
can be difficult. That`s why you should know that this won`t
happen with your Python learning journey.
17. Getting started
Finding an Interpreter
Before we start Python programming, we need to have an
interpreter to interpret and run our programs.
• There are many interpreters available freely to run Python
scripts like IDLE (Integrated Development Environment) that
comes bundled with the Python software downloaded from
http://python.org.
Examples: Spyder, Pycharm, Jupyter Notebook, etc.
• Online interpreters like https://ide.geeksforgeeks.org that can
be used to run Python programs without installing an
interpreter.
• Anaconda (https://www.anaconda.com) – a distribution of the
Python and R programming languages for scientific computing,
that aims to simplify package management and deployment.
18. Getting started
Writing our first program:
Just type in the following code after you start the interpreter.
print(“Hello World")
19. Fundamentals of Python
Python Comments
Comments are useful information that the developers provide to
make the reader understand the source code. It explains the logic
or a part of it used in the code. There are two types of comment in
Python:
• Single line comments: Python single line comment starts with
hashtag symbol with no white spaces.
# This is Comment
20. Fundamentals of Python
Python Comments
Comments are useful information that the developers provide to
make the reader understand the source code. It explains the logic
or a part of it used in the code. There are two types of comment in
Python:
• Multi-line string as comment:
Python multi-line comment is a piece of text enclosed in a
delimiter (“””) on each end of the comment.
“””
This would be a multiline comment
in Python that
spans several lines,
Hanji
“””
21. Fundamentals of Python
Built-in types
There are many kinds of information that a computer can process,
like numbers and characters. In Python (and other programming
languages), the kinds of information the language is able to
handle are known as types. Many common types are built into
Python – for example integers, floating-point numbers and strings.

An integer (int type) is a whole number such as 1, 5, 1350 or -34.
1.5 is not an integer because it has a decimal point. Numbers with
decimal points are floating-point numbers. Even 1.0 is a floating-
point number and not an integer.

Built-in types
There are many kinds of information that a computer can process,
like numbers and characters. In Python (and other programming
languages), the kinds of information the language is able to
handle are known as types. Many common types are built into
Python – for example integers, floating-point numbers and strings.
Floating-point numbers
Floating-point numbers (float type) are numbers with a decimal
point or an exponent (or both). Examples are 5.0, 10.24, 0.0, 12.
and .3

Strings
A string (type str) is a sequence of characters.
Strings in python are surrounded by either single quotation marks,
or double quotation marks.
print("Hello")
print('Hello')

Variables
Variable is a label for a location in memory.
It can be used to hold a value.
To define a new variable in Python, we simply assign a value to a
label. For example, this is how we create a variable called count,
which contains an integer value of zero:
# define variable count
count = 0

Python has some rules that you must follow when forming an
identifier:
• it may only contain letters (uppercase or lowercase), numbers
or the underscore character (_) (no spaces!).
• it may not start with a number.
• it may not be a keyword.
29. Fundamentals of Python
Variables
Variables in Python are not “statically typed”. We do not need to
declare variables before using them or declare their type. A
variable is created the moment we first assign a value to it.
# An integer assignment
age = 45
# A floating point
salary = 1456.8
# A string
name = "John"
print(age)
print(salary)
print(name)

Operators
Operators are the main building block of any programming
language. Operators allow the programmer to perform different
kinds of operations on operands. These operators can be
categorized based upon their different functionality.
31. Fundamentals of Python
Operators
• Arithmetic operators:
Arithmetic operators are used
to perform mathematical
operations like addition,
subtraction, multiplication and
division.
# Examples of Arithmetic Operator
a = 9
b = 4
# Addition of numbers
add = a + b
# Subtraction of numbers
sub = a - b
# Multiplication of number
mul = a * b
# Division(float) of number
div1 = a / b
# Division(floor) of number
div2 = a // b
# Modulus (remainder)
mod = a % b
# Exponent (power)
pwr = a ** b
32. Fundamentals of Python
Operators
• Arithmetic operators
Operator precedence
• Python has a specific and predictable way to
determine the order in which it performs
operations. For integer operations, the
system will first handle brackets (), then **,
then *, // and %, and finally + and -.
• If an expression contains multiple operations
which are at the same level of precedence,
like *, // and %, they will be performed in
order, either from left to right (for left-
associative operators) or from right to left
(for right-associative operators).
All these arithmetic operators are left-
associative, except for **, which is right-
associative.
# Examples of Arithmetic Operator
a = 9
b = 4
# Addition of numbers
add = a + b
# Subtraction of numbers
sub = a - b
# Multiplication of number
mul = a * b
# Division(float) of number
div1 = a / b
# Division(floor) of number
div2 = a // b
# Modulus (remainder)
mod = a % b
# Exponent (power)
pwr = a ** b
33. Fundamentals of Python
Operators
• Relational Operators:
Relational operators compares
the values. It either returns
True or False according to the
condition.
• == equal to
• != not equal to
• > greater than
• < less than
• >= greater than or equal to
• <= less than or equal to
# Examples of Relational Operators
a = 13
b = 33
# a > b is False
print(a > b)
# a < b is True
print(a < b)
# a == b is False
print(a == b)
# a != b is True
print(a != b)
# a >= b is False
print(a >= b)
# a <= b is True
print(a <= b)
34. Fundamentals of Python
Operators
• Logical Operators:
Logical operators perform
Logical AND, Logical OR and
Logical NOT operations.
# Examples of Logical Operator
a = True
b = False
# Print a and b is False
print(a and b)
# Print a or b is True
print(a or b)
# Print not a is False
print(not a)
35. Fundamentals of Python
Exercise
What are the results of the following operations and explain why:
15 + 20 * 3 = ?
13 // 2 + 3 = ?
31 + 10 // 3 = ?
20 % 7 // 3 = ?
36. Fundamentals of Python
Basics of data Input
• input(): This function first
takes the input from the user
and then evaluates the
expression, which means
Python automatically identifies
whether the user entered a
string or a number or list.
# input() example
name = input(“Enter your name:”)
print(name)
37. Fundamentals of Python
Python Indentation
Python uses indentation to highlight the blocks of code.
Whitespace is used for indentation in Python. All statements with
the same distance to the right belong to the same block of code. If
a block has to be more deeply nested, it is simply indented further
to the right. You can understand it better by looking at the
following lines of code.
# Python program showing
# indentation
university = ‘NEHU'
if university == ‘NEHU’:
print(‘Hi, NEHU student!')
else:
print(‘The university is not NEHU')
print('All set !')
38. Fundamentals of Python
Selection
Selection in Python is made using the two keywords ‘if’ and ‘elif’
and else (elseif)
# Python program to illustrate
# selection statement
mark = 34
if mark >= 80:
print(“Grade is A”)
elif mark >= 65:
print(“Grade is B”)
elif mark >= 50:
print(“Grade is C”)
else:
print(“Grade is D”)

Selection
Selection in Python is made using the two keywords ‘if’ and ‘elif’
and else (elseif)
# Python program to illustrate
# selection statement
mark = 34
if mark >= 80:
print(“Grade is A”)
elif mark >= 65:
print(“Grade is B”)
else:
