Python 3 - functions beginners exercise-CodePudding

Python 3, functions.

there is the following exercise:

write a function that asks the user to enter his birth year, first name and surname. Keep each of these things in a variable. The function will calculate what is the age of the user, the initials of his name, and print them. for example: John Doh 1989 Your initials are JD and you are 32. age calculation depends on what year you are doing the track. you should use input, format etc.

the given answer is:

def user_input():
  birth_year = int(input("enter your birth year:\n")) 
  first_name = input ("enter your first name:\n")
  surname = input ("enter your surname:\n")
  print ("your initials are {1}{2} and you are {0} years old". format(first_name[0], surname[0],2021-birth_year))

when I run this the terminal stays empty, hope you could help, thank you in advance!

CodePudding user response：

Make sure to call your function, so that it gets executed:

def user_input():
    birth_year = int(input("enter your birth year:\n")) 
    first_name = input("enter your first name:\n")
    surname = input("enter your surname:\n")
    print("your initials are {1}{2} and you are {0} years old".format(first_name[0], surname[0], 2021-birth_year))

# Call it here
user_input()
