Accessing module level variables, from within a function in the module

Question

I\'d like to be able to do something like this:

#mymodule
var = None

def load():
    var = something()

Other module(s):

#secon         


        

Answer 1

Just change the function definition to:

def load():
    global var # this line has been added to the original code
    var = something()

Global variables are read-only from sibling methods. More accurately unless a variable is specified as global, Python consider it as local, but a read access to a local variable name will reach module-level scope if the name is not present in local scope.
