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.

CodePudding user response：

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

CodePudding user response：

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.
