age check python code example

Example 1: age check python

import datetime
try:
    current_year = datetime.datetime.now().year
    print(current_year)
    print('Must be over 18!')
    age = int(input('How old are you? '))

        print('You are over 18!')
        born_year = int(input('What year were you born in? '))
        born_year_output = current_year - born_year
        born_year_minus = born_year_output - 1
        if born_year_output == age:
            print('You are really over 18!')
            name = input('What is your first name? ')
            last_name = input('What is your last name? ')
            print(f'You are {age} years old and your name is {name} {last_name}')

        else:
            print('You are not over 18!')
            quit()
    else:
        print('you are not over 18!')
        quit()

    text_file = open("userdata.txt", "w")
    n = text_file.write(f'Name: {name} {last_name}, age: {age}. born in {born_year} \\')
    text_file.close()
except Exception as e:
    print(f'Error: {e}')
    quit()
