30 PointsWhy use a slice to copy list?
So I watching the video Introduction to slices.
In it he said to make a quick copy of your list you can use the following:
new_list = my_list[:]
and that makes a copy of your list into the variable new_list.
Why is that better than just writing:
new_list = my_list?

Treehouse Guest TeacherTry this in your shell
my_list = [1, 2, 3]
new_list = my_list
new_list.append(4)
print(my_list)
What comes out?

30 PointsHuh....ok. Thanks for pointing that out. Seems counter intuitive but explains a problem I was having in one of your challenges. Thank you very much!
