Python If-Else Condition

#python #webdev #django

Conditioning is the most basic operator in any programming language. Python provides some of the built-in additional tools which we'll be learning in the section of our python tutorial.

Example: To create a simple if statement.

    a=10 
    b=5

    if a > b:
        print("Yes the value of a is greater than b value.") 

    #PYTHON OUTPUT
    Yes the value of a is greater than b value.

If Else Conditional Statement

Example

    a=10
    b=11

    if a >= b:
        print("Yes the value of a is greater than b value.") 
    else:
        print("Yes the value of b is greater than a value.") 

    #PYTHON OUTPUT
    Yes the value of b is greater than a value.

Elif Conditional Statement

    user_role = 'STAFF'

    if user_role == 'ADMIN':
        print("Welcome Administrator")
    elif user_role == 'STAFF':
        print("Welcome Staff")

    #PYTHON OUTPUT
    Welcome Staff

Nested if-elif in python

Example: To check greater of 3 nos.

    a=10
    b=11
    c=9

    if a > b:
        if a > c:
        print('A is greater')
        else:
        print('C is greater')
    elif b > c:
        print("B is greater")
    else:
        print('C is greater')

    #PYTHON OUTPUT
    B is greater

Example: Short-Hand If Condition

    a=12
    b=14

    if b>a: print(b)

    #PYTHON OUTPUT
    14

Example: Short-Hand if-else condition

    a=15
    b=16

    print(a) if a>b else print(b)

    #PYTHON OUTPUT
    16

Example: Multiple conditioning use AND OR operator.

    a=35
    b=25
    c=33    
    if a>b and a>c:
        print('A is greater than B and C')
    // PYTHON OUTPUT
    A is greater than B and C
    a=30
    b=25
    c=33    
    if a>b or a>c:
        print('Because A is greater than B') #if any one condition is True
    // PYTHON OUTPUT
    Because A is greater than B
