Pass global variables to modules - Python

Question

I have a code module.py that is imported into my main.py so I can use its functions, which are defined with def . The imported module only has def functions.

There are some if statements in the functions that I'd wish to manipulate automatically from main.py .

Like for example

main.py

import module as md


BoolIfState=True

for i in range(10):
    md.runfunction(i)

module.py

def runfuntion(i):
   if BoolIfState:
        print i
   else:
        print i-10

return None

Here the definition of BoolIfState in main.py changes how runfunction from module behaves. I tried adding global BoolIfState inside the function but it didn't change the behavior.

Obviously, the actual codes are much more difficult but it's the same basic idea.

Is there a way to do this?

Edit: I am avoiding giving the variable as an input to the function because then it will become cluttered given all the variables that would need to be added. I need to the same thing to approximately 5 variables, and with it, the cleanliness of having functions defined inside the module are lost.

Answer 1

You could package all of the global variables into a singleton class ( singleton class example ).

This way you could maintain one class instance with member variables that could be used/accessed across your codebase.
