Conditionals and Control Flow

• Conditionals execute certain block (line or lines of code) depending on some condition
  • if-else:

    number = 11
    remainder = number % 2
    print(remainder)
    if remainder == 0:
        print('even')
    else:
        print('odd')
    

  • if-elif-else:

    total_marks = 600
    acheived_marks = 544
    average = (acheived_marks/total_marks) * 100
    
    if 90 <  average <= 100:
        print('A1')
    elif 80 <= average <= 90:
        print('A2')
    elif 70 <= average <= 80:
        print('B1')
    elif 60 <= average <= 70:
        print('B2')
    elif 50 <= average <= 60:
        print('C1')
    elif 40 <= average <= 50:
        print('C2')
    elif 32 <= average <= 40:
        print('D')
    elif 20 <= average <= 32:
        print('E1')
    elif 0 <= average <= 20:
        print('E2')
    else:
        print('average should in range of 0-100')
    
    

    • Exercise: Write a python program using if elif statements to findout the largest number among a b c

    a = 10
    b = 5
    c = 11
    
    print c is greater
