Key Concepts Explanation

Conditionals in Python

Conditionals in Python are implemented using the “if else” statements. These statements help in executing specific blocks of code based on certain conditions.


i = 5

if i % 2 == 0:

Ternary Operator

The ternary operator in Python allows for concise conditional expressions with a one-liner syntax.


i = 5
print("even") if i % 2 == 0 else print("odd")

Hands-On Tasks

  1. Task 1
    Determine the category of the baby based on age in months.

    • Print New Born or Infant till 6 months.
    • Print Toddler from 7 to 18 months.
    • Print Grown up from 19 to 144 months.
    • Print Youth from 145 to 216 months.
    age = int(input('Enter age in months: '))
    if age <= 6:
        print('New Born or Infant')
    elif 7 <= age <= 18:
    elif 19 <= age <= 144:
        print('Grown up')
    elif 145 <= age <= 216:
  2. Task 2
    Check if the number is even or divisible by 3.

    n = int(input('Enter integer: '))
    if n % 2 == 0 or n % 3 == 0:
        print(f'Number {n} is even or divisible by 3')
  3. Task 3
    Check if the number is even and divisible by 3.

    n = int(input('Enter integer: '))
    if n % 2 == 0 and n % 3 == 0:
        print(f'Number {n} is even and divisible by 3')
    elif n % 3 == 0:
        print(f'Number {n} is divisible by 3 but not even')
    elif n % 2 == 0:
        print(f'Number {n} is even but not divisible by 3')


In conclusion, understanding conditionals in Python is crucial for controlling the flow of your programs based on specific conditions. By mastering conditionals, you can write more dynamic and flexible code.
