The method pop()
return the item popped and modified the list in-place
. So newlist
contains the popped item and not the new list. change the returned item to list
instead of newlist
.
Also, it is not the best choice to use the name of a built-in type list
as a variable name. This overrides the name locally to the function and prevents list()
from working. Try using list1
or num_list
, etc.
Post back if you need more help. Good luck!!
