1. PYTHON ABOUT BASICS
WHY PYTHON (.py)?
 Considering other programming languages, python is the most easy and simplest
programming language to be understood by both programmers as well as non-
programmers.
 It has easy syntax similar to simplified pseudo-code as its syntax mostly follows the simple
language to outline the code.
 Python has plenty number of inbuilt libraries that makes easy use of the predefined libraries
by the programmers making the code short and simplified in syntax.
 In addition to the standard libraries, python also has extensive collection of freely available
add-on modules, libraries, tool-kits, etc.
 Python makes the programs more productive and less complex as compared to other
programming languages.
SYNTAX
There are generally 3 parts of a program:
[Input: Processing: Output]
 Input syntax:
name=input()
print(name)
This is the basic syntax used to input data in python.
By default python takes input data as string, therefore if we want to input integers or float values in
python, then we have to use casting method. Generally 3 types of casting is used [int,float,string].
Casting syntax : int(), float(), str().
 Input numbers:
Num=int(input())
Num2=float(input())
 Output syntax:
Print(“hello world”)
USEFUL POPUPS
 If we have to comment a line in python then we use (#) symbol, i.e. we want to write a line
for only our understanding and not to be executed in a program then we comment that
particular word or line.
 This is done in two ways:
 SINGLE LINE COMMENT (#)

2.  MULTI LINE COMMENT (“”” “””)
 The indentation in Python is very important, it refers to the spaces at the beginning of a
code line. While in other programming languages the indentation in code is for readability
only. Python uses indentation to indicate a block of code.
VARIABLES
Variables are named memory locations where data of a program is stored.
In python variables are created when you assign a value in the code.
DATA TYPES
In python tension of data types is not required, since python is dynamic in nature i.e. at runtime the
interpreter understands datatype according to the value entered.
By default python assumes data entered is of string type.
Data types in python:
Text Type: string
Numeric Types: integer, float, complex
Sequence Types: list, tuple, range
Mapping Type: dictionary
Set Types: set, frozen set
Boolean Type: boolean (true or false)
Binary Types: bytes, byte array, memory view
You can get type of data type by using function: type()
OPERATORS:
