When I run my python file the normal function doesn't do anything happens, nothing is outputted, how can I display the function

Question

I am writing a function which is supposed to get the user's response, yet when I run the file nothing happens, its just an empty screen, how do I fix that? I tried searching up in stackoverflow but I couldnt find what im looking for, thanks in advance :)

def get_user_response():
  while True:
    try:
      print ('Enter the number of clickbait headlines to generate: (0 to exit)')
      user = int(input('> '))
      print ('HEADLINES')
      if user == 0:
        for x in range (0,4):
          l = "Exiting Program" + "." * x
          print (l, end="\r")
          sleep(1)
        break
      else:
        print ('a')
    except:
      print ('Invalid - Enter an integer')

You’ve defined a function but if you don’t call it nothing will happen — Sami Kuhmonen, Apr 10 '22 at 06:12

You defined a function but never called it anywhere. That's why the program is not running in the first place. Just write

get_user_response()

anywhere outside of the function.

Also consider wrapping only the user input line into the try except statement, otherwise you will literally catch every possible error that might occur in your function without ever getting an error message.

Why do you think that? – Sören Apr 10 '22 at 07:22
After your comment i tried it with Python 3.10.3 and your right i think because i tried this ---> `def hello(): while True: print("hello") hello() ` 'and it printed hello . Then the problem is with the version python or something different ? – berk Apr 10 '22 at 14:12
No. See Dominic K.'s answer. – Sören Apr 10 '22 at 14:27
