Python Copy a List
Copy a List
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
.
There are ways to make a copy, one way is to use the built-in List
method
copy()
.
Example
Make a copy of a list with the copy()
method:
thislist = ["apple", "banana", "cherry"]
mylist
= thislist.copy()
print(mylist)
