Comparison between =, == and .copy() for "list":
i) = and == do not create new lists. Sush assignment just copies the reference to the list.
ii) [:], .copy and copy.copy() created copies from the original list and then the new lists will not be changed when the original lists are changed.

============================================

=, ==, .copy(), copy.copy() for "list": code:

Output:

Copy lists: code:
          =, ==, .copy(), copy.copy() for "list"
Output:
