Answer 1

a = [1, 2, 3]
b = a
c = a[:]

b is the same list as a, which means you just gave it a different name, if you change elements in b, they will be changed in a too, as they are one single list with two different names.
c is just a part of a, and in this case the whole list, but it is independent, operations that you make on c won't affect a.
