I bit of a mix-up with words here. A variable can be a class variable
or a global variable (wrt the module).. not both.

You could have posted the error message... Two things are wrong here.
The first, if some_methos() is a method of ClassName then it should have
at least one parameter, which is the instance of the class (i.e.
"self"), so
def some_methos(self):
The second problem is that global_var is not local so you need to
specify the scope. You can either use
print ClassName.global_var
or
print self.global_var
I'm not sure which one is better though I prefer the former because it
makes it clearer to the reader that it's a class variable and not an
instance variable.
