Change Var. from Within a Class?

Dec 21st, 2008

Hello, I'm new to Python and I'm using Pydev. I'm having a problem: I have several classes and several variables outside the classes. I want to change a variable outside the classes from within a class:

e.g.

# Class

class name_change(object):
     """Change a text variable outside this class"""

     def name_change(self):     
          name = "elvenstruggle"


# Variable

name = ""


# Call Class

class = name_change()

Basically I want to change the name variable through the class, and I'm having trouble. It's not working! Please help me! Thanks a lot!

Here is one way to do it:

 Python Syntax (Toggle Plain Text) 
>>> class test(object):
... 	def change_var(self, name, value):
... 		globals()[name] = value
... 		
>>> var = 123
>>> obj = test()
>>> obj.change_var('var', 456)
>>> var
456
>>>
>>> class test(object):
... 	def change_var(self, name, value):
... 		globals()[name] = value
... 		
>>> var = 123
>>> obj = test()
>>> obj.change_var('var', 456)
>>> var
456
>>>
