How to share variables between methods in a class? [duplicate]

Question

I'm looking for a way to make a variable set by one method/function in a class accessible by another method/function in that same class without having to do excess (and problematic code) outside.

Here is an example that doesn't work, but may show you what I'm trying to do :

#I just coppied this one to have an init method
class TestClass(object):

    def current(self, test):
        """Just a method to get a value"""
        print(test)
        pass

    def next_one(self):
        """Trying to get a value from the 'current' method"""
        new_val = self.current_player.test
        print(new_val)
        pass

You set it in one method and then look it up in another:

class TestClass(object):

    def current(self, test):
        """Just a method to get a value"""
        self.test = test
        print(test)

    def next_one(self):
        """Trying to get a value from the 'current' method"""
        new_val = self.test
        print(new_val)

As a note, you will want to set self.test before you try to retrieve it. Otherwise, it will cause an error. I generally do that in __init__:

class TestClass(object):

    def __init__(self):
        self.test = None

    def current(self, test):
        """Just a method to get a value"""
        self.test = test
        print(test)

    def next_one(self):
        """Trying to get a value from the 'current' method"""
        new_val = self.test
        print(new_val)
