I have made two py files, in which main.py contains:
import module
module.Print("This should not appear.")
module.Silence = False
module.Print("This should appear.")
The module imported is module.py which contains:
Silence = True
def Print(Input, Sil= Silence):
if Sil == False:
print(Input)
The expected result should be:
This should appear
The result:
The issue is that you've defined your Print function with a default argument of True (since Silent == True when this module is imported, and the function created). Changing the module variable, Silent to False later isn't going to affect this function definition in any way. It's already set in stone.
You could achieve what it looks like you want to doing something like (in module.py):
Silence = [True]
def Print(Input, Sil= Silence):
if Sil[0] == False:
print(Input)
...
And then setting module.Silence[0] = False in main.py.
[I'm assuming the goal here was to call the function without passing in an explicit Sil argument. You can certainly just pass in an explicit second argument and have the function perform exactly how you expect instead]
I think you are looking for a function with a default setting that can be dynamically changed. This will use the global Silence only if the sil argument is omitted in Print() function call.
def Print(input, sil=None):
if sil is None:
sil = Silence
if not sil:
print(input)
Printmethod. So it is always taking the default argument you defined asFalse. When you callPrintjust pass your second argument:module.Print('stuff', module.Silence)
