Objects in python

Question

What does it mean to “reference an object”?
I was trying to create a code where it uses a function from a different class. I was told i have to reference an object before adding the function. What does this mean?

Thanks

Answer 1

Functions in classes are called methods, and they're supposed to be only accessible via the class and its instances.

Take a simple Python list for example.

a_list = [1, 3, 2]
a_list.sort()

If you print out that list later, it will be sorted.

But sort belongs to lists, so you always have to call it *with* a specific list (an object/instance) as you just saw here.

Luna, may be you can post or link your code here so that we can have a clear picture from what happens.
