Trying to use a variable that is inside a function in another function

Question

So I am trying to use a variable that is inside a function in another function.

One of them is the "message.py" file, that is in the folder "properties". The file looks like this:

def nachricht():
    global msg
    msg = input("Type: ")
    return msg

The other file is the "badwords_check.py", that is in the folder "module". This file looks like this:

from properties.message import msg
from properties.badwords import BadWords

def badwords_check():
  if any(word in msg for word in BadWords):
    print("Dont use that word!")
    
  else:
    print("Message send!")

The problem now, is that I can't import "msg" from "message.py".

The error code looks like this:

from properties.message import msg
ImportError: cannot import name 'msg' from 'properties.message'

I had tried things like: Global, with/without function(without the function it works, but I need it with a function because some other code and files) and I tried return.

Answer 1

You need to declare the global variable outside the function at the top and then you can modify it inside your function using global msg .

msg= ''
def nachricht():
    global msg
    msg = input("Type: ")
    return msg

Answer 2

To add on to Vaibhav's answer, the function nachricht() is never being called in badwords_check.py.

Hence, there is no input being taken and the variable msg also doesn't exist.

While declaring msg as a global variable, the function should also be called.

from properties.message import *
from properties.badwords import BadWords

#use nachricht()
#then use the below function

def badwords_check():
  if any(word in msg for word in BadWords):
    print("Dont use that word!")
    
  else:
    print("Message send!")

If nachricht() is not used, then msg will simply be a empty string.
