How to use one list in different functions, Python

Question

So I do not want to use global variables, and I have a list that I want to use i different functions. How do I do it?

I got this so far:

class List:
    def __init__(self):
        self.myList = list()

def func1():
    l = List()
    l.myList.append(22)

def func2():
    l.myList.append(34)

I get an error when executing the second function and the question is how I continue to put elements into myList using different functions.

Thank you

I guess this is just for demonstration, but the class here adds nothing at all. — Daniel Roseman

Pass the list as an argument to the two functions:

def func1(l):
    l.myList.append(22)

def func2(l):
    l.myList.append(34)

def driver():
    l = List()
    func1(l)
    func2(l)

l object created in finc1:

l = List()

So, it's local. You should consider scope of variables and objects.
