Python, Import config.py

Question

# config.py
white = (255,255,255)

# main.py
import config
print(white)

# output:
Traceback (most recent call last):
  File "C:\...\Test\Test2.py", line 2, in <module>
    print(white)
NameError: name 'white' is not defined

Process finished with exit code 1

# wanted output
(255, 255, 255)
 
Process finished with exit code 0

Hello

I want to create a variable in a config.py file, import that file into main.py, and use the variable. But the variable does not become available in main.py. I don't want to change the variable inside main.py, I only want to reference to it. What am I doing wrong?

The code provided is a simplification of the actual code and acts as an example.

One solution I can find is the following. But what shall I do if I have got multiple variables?

# main.py
import config
white_new = config.white
print(white_new)

import config.py would raise an error. Please always provide a minimal reproducible example But assuming you actually did import config, then why did you expect to be able to print(white)? You would need to use config.white. Which is probably what you should use — juanpa.arrivillaga

"But what shall I do if I have got multiple variables?" you should just use config.whatever. You could also use a from config import <list of variable> or even from config import *, but the latter is considered a bad practice. Really, just using import config and config.white, config.yellow or whatever is the best way — juanpa.arrivillaga

Just do:

# main.py
from config import white
print(white)

For multiple variables:

from config import white, variable_1, variable_2, ...
