Question

How can I take one variable from one function and use it in another function without having to make that variable global?

Answer 1

You have basically two choices.

One is to pass it to the second function as a parameter. (If you want the first function to see changes to the value, it needs to be a reference type (e.g. a dict/list) and you have to not overwrite the object, only modify it (e.g. a.append(b) rather than a = a + [b]).

The second is to define a class that can be used as a singleton. Technically, this is still defining something ‘globally’, but it lets you keep things grouped:

class FooSingleton(object):
    class_var = "foo"

def func1():
    FooSingleton.class_var = "bar"

def func2():
    print(FooSingleton.class_var)

(You could also do this with a dict instead of a class; matter of preference.)
