Is it a good practice to set variables outside def's and classes in a module to use them as global by using import?

I suppose this behaviour would generate something like a static variable type from Java, where your variable exists and is set even without a specific instance of a class. Appreciate any insights and/or comments. Cheers!

Example:

in someCustomModule.py

someVar = "hey I get assigned at import"

def doSomething(): ...

in myExecutedModule.py

import someCustomModule.py

....

print(someCustomModule(someVar))

...

Terminal

$ python myExecutedModule.py

$ hey I get assigned at import

If it makes sense for the modularity then I suppose it's okay, but I struggle with finding an example that would benefit from this. In most cases I can think of you would be better of using json or other regular textfiles.
