OF 
PYTHON 
WHAT IS PYHTON 
PROGRAMMING LANGUAGE ?
• PYTHON IS A HIGH-LEVEL PROGRAMMING LANGUAGE.
• IT IS SIMPLE AND EASY TO UNDERSTAND.
• IT HAS ENGLISH-LIKE SYNTAX.
• PYTHON IS USED IN WEB, AI, DATA SCIENCE, AND AUTOMATION.
• IT IS FREE, OPEN-SOURCE, AND CROSS-PLATEFORM .
Features Of Programming Language
• SIMPLICITY : -  EASY TO LEARN AND USE.
• READABIL ITY : -  CODE SHOULD BE EASY TO READ AND 
UNDERSTAND.
• PORTABIL ITY : -  CAN RUN ON DIFFERENT 
COMPUTERS/OPERATING SYSTEMS.
• SECURITY : -  PROVIDES ERROR HANDLING AND PROTECTS 
FROM MISUSE .
• REUSABILITY : -  SAME CODE CAN BE USED AGAIN IN OTHER 
PROGRAMS .
Application of python 
       
•WEB DEVELOPMENT
•DATA SCIENCE & ML
•AI & AUTOMATION
•GAME DEVELOPMENT
   
Data Types(Basic+ Collections)
 BASIC TYPES:-
• Numeric : Int, Float, Complex
• String: Str
• Boolean: True/False
• None: None type A = 10                    # Int
 COLLECTION TYPES:- B =  “Hello”           # String
• C =  [1,2,3]           #  ListList : Odered, Changeable
• Tuple : Odered, Unchangeable
• Dictionary : Key: value pairs
OPERATORS:-
 OPERATORS: 
• Arithmetic : Used for mathematical operations (+, -,  /, %)
• Relational : Used to compare values(True/False) (>, 5:    
                                           print(“x is greater than 5”)       [output: x is greater than 5]
If-else condition example:- 
                                                                                                                   n  u  m    =    4                                   
     if num % 2 == 0:
                                                    print(“Even number”)
     print(“Odd number”)           [Output: Even number]
If- Elif-else example:- 
marks = 75
if marks >= 90:
    print(“Grade A”)
Elif marks >= 60:
      print(“Grade B”)       
      else:
                                                      print(“Grade C”)                  [Output: Grade B]
                                  
Functions + String & List Methods
  FUNCTIONS:
• Built-in (print(), len())
• Def add(a, b):User-defined (def keyword)
       return a + b
   STR ING  METHODS:  UPPER( ) ,  LOWER( ) ,  REPL ACE( ) Print(add(5, 3))
   L IST  METHODS:  APPEND( ) ,  POP ( ) ,  SORT( )
