Add input validation for age field

[Shweyy123]

Feature description

def get_age_input():
age_input = input("Enter your age: ")
if age_input.isdigit():
age = int(age_input)
print(f"Your age is {age}")
else:
print("age is not valid")

get_age_input()

What this does:

1. Takes input from the user.

2. Checks if the input only contains digits using .isdigit().

3. If it is digits, it converts it to an int and prints it.

4. If it’s not (e.g., letters, special characters), it prints "age is not valid".
