The presentation provides an introduction to the Python programming language. It discusses the origin of Python, its creator Guido van Rossum, and its key features like readability, indentation, variables, data types, decision making, control flow, functions, and object-oriented programming. The presentation was given by Amit Singh, with his university roll number, on the topic of introducing Python.

4. INTRODUCTION
 Python is an open source , general purpose programming language that is easy to
read .
 It is an interpreted language , which do not need to be compiled to run .
 Python is high level language that will make a programmer focus on what to do
instead of how to do .
 Python has been designed to emphasize on code readability with its significant use
of whitespace .
 Writing programs in python is less time consuming compared to any other
languages .

5. ORIGIN
SIR GUIDO VAN ROSSUM
Python is an interpreted high-level
programming language for general-
purpose programming .Created by
“GUIDO VAN ROSSUM “ and first
released in 1991. Python has a design
philosophy that emphasizes code
readability. Notable using significant
white space .it provides construct the
enable clear programming on both
small an large scales .

6. FEATURES
 Easy to code
 Free and open source
 Object and oriented language
 Gui programming support
 High-level language
 Extensible feature
 Python is portable language
 Python is integrated language

7. INDENTATION
Indentation is a very important concept of python because without proper indenting
the python code , you will end up seeing INDENTATION ERROR and the code will not
get compiled .
Python indentation is a way of telling a python interpreter that the group of
statements belongs to a particular block of code . A block is a combination of all
these statements . Block can be regarded as the grouping of statements for a specific
purpose .

8. VARIABLES
Variables are nothing but reserved memory locations to store values .
This means that when you create a variable you reserve some space in memory .
Example :-
X=5
Y=“john”
print(x)
print(y)

9. OPERATORS
Operators are used to perform operations on variables and operators are the main
building block of any programming language . Operators allow the programmer to
perform different kinds of operations on operand values .
Example :-
print (10+5)
 Python divides the operators in the following groups:-
 Arithmetic operators
 Assignment operators
 Comparison operators
 Logical operators
 Identity operators
 Membership operators
 Bitwise operators

10. DATATYPES
Data types are the classification or categorized of data items . Pythons supports the
following built-in data types
Following are the standard or built –in data types of python :-
 Numeric
 Sequence type
 Boolean
 Set
 Dictionary

11. DECISION MAKING
Decision in a program are used when the program has conditional choices to execute
a code block . Let’s take an example of traffic lights , where different colors of lights lit
up in different situations based on the conditions based on the conditions of the road
or any specific rule .
 IF STATEMENT
 IF - ELSE STATEMENT
 NESTED IF STATEMENTS
 IF – ELIF LADDER

12. CONTROL FLOW
Loops in programming come into use when we need to repeatedly Execute a block of
statements . For example : Suppose we want to print “HELLO WORLD” 10 times . This can be
done with the help of loops . The loops in python are :-
 While and while-else loop
 For and for-else loop

13. FUNCTIONS
 Functions are generally the block of codes or statements in a program that gives
the User the ability to reuse the same code which ultimately saves the excessive
use of memory ,acts as a time saver and more importantly . Provides better
readability of the Code .
 So basically , a function is a collection of statements that perform some specific
task and return the result to the caller .
 A function can also perform some specific task without returning anything .

14. OOPS
 Object – oriented programming (OOP) is a method of structuring a program by bundling related
properties and behaviors into individual object .
Class
 A class is a blueprint for the object . We can think of class as a sketch of a parrot witg labels . It
contains all the details about the name , colors , size etc.
Object
 An object (instance) is an instantiation of a class . When class is defined , only the description for
the object is defined . Therefore , no memory or storage is allocated .

15. CONCLUSION
At last we want to say that , python is a fully-fledged programming language. Any
code you can download the python package index, or anywhere else , can be
malicious and would almost certainly go unnoticed by most people’s firewalls .
