What do I pass as the first parameter “object” to the function setattr(object, name, value), to set variables on the current module?
For example:
setattr(object, “SOME_CONSTANT”, 42);
giving the same effect as:
SOME_CONSTANT = 42
within the module containing these lines (with the correct object).
I’m generate several values at the module level d….
I want to define a constant that should be available in all of the submodules of a package. I’ve thought that the best place would be in in the __init__.py file of the root package. But I don’t know how to do this. Suppose I have a few subpackages and each with several modules. How can I access that variable from these modules?
Of course, if this ….

From my understanding, Python has a separate namespace for functions, so if I want to use a global variable in a function, I should probably use global.

>>> sub = [‘0’, ‘0’, ‘0’, ‘0’]
>>> def getJoin():
… return ‘.’.join(sub)
…

I know I should avoid using global variables in the first place due to confusion like this, but if I were to use them, is the following a valid way to go about using them? (I am trying to call the global copy of a variable created in a separate function.)
x = “somevalue”
def func_A ():
global x
# Do things to x
return x
def func_B():

How do I create or use a global variable inside a function?
How do I use a global variable that was defined in one function inside other functions?
