Using variables from other Python file

问题

I am making a little game thing in Python, I'm still fairly new to this. I am trying to access a variable in another file by using import, but it keeps saying

AttributeError: module 'core temp' has no attribute 'ct'

This is my code I am trying to run:

elif cmd == "temp":
    if core.ct < 2000:
      print(colored("Core temperature: "+core.ct+"°C", "green"))
    elif core.ct < 4000:
      print(colored("Core temperature: "+core.ct+"°C", "yellow"))
    elif core.ct >= 3000:
      print(colored("Core temperature: "+core.ct+"°C", "red"))

I am importing coretemp like this: import coretemp as core

This is the code in coretemp.py:

from time import sleep as wait
import coolant as c

ct = 10

while True:
    if c.coolactive == False:
        ct = ct + 1
        wait(.3)
    else:
        ct = ct - 1
        wait(1)

I've been stuck on this problem for ages!

PS: sorry if things aren't formatted right, I'm on mobile and it's hard.

回答1:

The only way I can see you would get this error is if the coolant module also imports coretemp. (BTW, I am assuming here the space in core temp was a copy/paste error)

If coolant imports coretemp it will be accessing a copy of the module as it existed when coretemp imported coolant. That would mean ct is not yet defined.

Note that the import in main will never complete as coretemp.py contains an infinite loop at the top level: main will simply wait for ever for the module it is importing to finish executing.
