Python - Copy Lists

You cannot copy a list simply by typing list2 = list1 , because: list2 will only be a reference to list1 , and changes made in list1 will automatically also be made in list2 .

You can use the built-in List method copy() to copy a list.

Another way to make a copy is to use the built-in method list() .

You can also make a copy of a list by using the : (slice) operator.
