This document provides an introduction to the Python programming language. It discusses that Python is an object-oriented and general purpose language used for tasks like web search, gaming, finance, and data analytics. It can be run through a command prompt, text file, or integrated development environment. The document reviews key Python concepts like its interpreted nature, program structure, modules, expressions, printing, and manipulating time and LEDs through importing modules.
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.

Python is a widely used programming language that offers several unique features and advantages compared to languages like Java and C++. Our Python tutorial thoroughly explains Python basics and advanced concepts, starting with installation, conditional statements, loops, built-in data structures, Object-Oriented Programming, Generators, Exception Handling, Python RegEx, and many other concepts. This tutorial is designed for beginners and working professionals.
Python is an interpreted, object-oriented, high-level programming language with dynamic semantics. Its high-level built in data structures, combined with dynamic typing and dynamic binding, make it very attractive for Rapid Application Development, as well as for use as a scripting or glue language to connect existing components together. Python's simple, easy to learn syntax emphasizes readability and therefore reduces the cost of program maintenance. Python supports modules and packages, which encourages program modularity and code reuse. The Python interpreter and the extensive standard library are available in source or binary form without charge for all major platforms, and can be freely distributed.

A Python Developer is in charge of writing, developing, delivering, and debugging development projects, which are often server-side (or back-end). They may, however, assist firms in developing their technical foundation. They may be requested to produce an application for your employer, design the framework for your code, build tools as needed to complete the task, build websites and integrable systems, or publish new services.

2. Why Python?Why Python?
Python is what is referred to as an object-oriented programming
language (OOP)
Python is a general purpose programming language. That means you
can use Python to write code for a number of programming tasks.
◦ Google search engine
◦ Gaming
◦ Processing financial
transactions
◦ Data Analytics
◦ Physical Programming
Simple
Less Syntax
Extensive User Community
Interpreted
3. Interpreted?Interpreted?
Python is interpreted, which means that
python code is translated and executed by
an interpreter one statement at a time.
This means you can run commands/code
on the command prompt…
Through a command
prompt with a text file…
Using an IDE
5. Parts of a Python ProgramParts of a Python Program
Def: Source Code is the program text
entered into an interpreter by the
programmer.
◦ The saved file is referred to as, the source file.
◦ The main file in a python program, called main
◦ Can program on the command prompt
The extension to a python source file is “.py”
◦ Xcel - .xls
◦ Power Point - .ppt
Two main parts to a source file
◦ Modules
◦ Main code
6. Good programming proclamationsGood programming proclamations
Using comments to denote programs or
sections of code
◦ A comment beginning with # is called a single-line comment
because it terminates at the end of the current line.
◦ You also may use a multi-line comment—possibly containing
many lines—begins with ’’’ and ends with ’’’.
You use blank lines, space characters and tab characters
(i.e., “tabs”) to make programs easier to read.
◦ Together, these characters are known as white space.
◦ White-space characters are USUALLY ignored by the interpreter.
◦ Python has its own rules with white space
7. ModulesModules
A module is a python source file that has prewritten
python code.
These predefined files allow users to utilize code that has
been previously developed.
◦ Don’t have to recreate the wheel, just use the wheel and
improve on the technology.
math
time
Gpiozero
Os
Code: Importing modules
import module_name
from module_name import class_name
8. ExpressionsExpressions
• A programming expression is a
combination of symbols to represent a
value.
• One side of an equation
• Ex.
• 5+7
• False
• print()
• led.on()
9. Printing a Line of TextPrinting a Line of Text
print(“ “)
Anything placed inside the quotes will be printed on the screen
upon execution of the print command.
10. Manipulating TimeManipulating Time
The time module is a popular module which
provides functions for working with times and
converting between them.
◦ sleep
◦ local time
◦ epoch time
Code:
◦ Importing time module
import time
◦ Using time functions
time.sleep(#)
time.localtime(time.time())
11. Manipulating LED’sManipulating LED’s
The Raspberry Pi comes with a library RPi.GPIO that allow
the manipulation of GPIO pins: s
◦ Setup pins as inputs or outputs
◦ Read inputs
◦ Set output levels
However, gpiozero is a wrapper library that is built on top
of RPi.GPIO to provide a simpler interface to manipulate
the pins.
Code:
◦ Importing gpiozero module
import gpiozero
◦ Using led functions and objects
LED(pin#).on()
LED(pin#).off()
LED(pin#).blink()
