Beginner trying to understand functions.

Thanks for the extra tips Ivan and Bruno. Here is how the program
looks now. Any problems?



import sys

def get_name():
    name = input('Please enter your name: ')
    print('Hello', name)

def get_age():
        try:
            return int(input('Please enter your age: '))
        except ValueError:
            print('That was not a valid number. Please try again.')
            return get_age()

def check_age(age,min=18,max=31):
    if age < min:
        print('Sorry, too young.')
    elif age >= max:
        print('Sorry, too old.')
    else:
        print('Come on in!')

def again():
    response = input('Try again? Y or N: ')
    while response != "Y":
        if response == 'N':
            print('Program finished.')
            input('Press any key to exit.')
            sys.exit()
        else:
            return response
    run()

def run():
    get_name()
    a = get_age()
    check_age(a)
    again()

run()
