Variable from other files
bossotron13 (67)

From all the google searches I’ve been told to use, from file import Variable but when i do that, it runs all the code inside of file, and is there a way i can import all the variables not one by one. Ive tried from file import * but that just runs all the code.

Let's say you have two files, and, in the same folder.

If you write the following into and save it:

power = 9001

Then in, you can write this:

import variables
print(variables.power) # 9001 gets printed

You can also do the same thing like so

from variables import power
print(power) # 9001 gets printed

If you have some code in that you don't want to run when it is imported, then you can do this:

power = 9001
if __name__ == '__main__':
    # Code in here does not run when this file is imported,
    # it only runs when the file is executed.

If looks like above, then you can import it without the ... part being run.

If there's some other issue you're running into, please put your code in a repl and share it here so we can help better.

You can do import file Then do file.variablename when you want to access a variable

@mat1 but when you import it just executes the whole code

@bossotron13 Well, the variable won't be set if the code isn't run, so that's necessary. If you want parts of the code to not run while importing, put them in a function and call it later

@mat1 so yes but i imported it after the variables like so,
power = 3
import level2
and i try to print in level2 and it says not defined, any help?

@bossotron13 In level2, add from main import power and then you can use the variable.
