Python Program:

Define a method to append another list to your originallist.

output result:

mylist1 = [2,3,4,5]

mylist2 = [6,7,8,9]

Append mylist2 to mylist1 sot that mylist1 =[2,3,4,5,6,7,8,9]

MY CODE: Not correct, but I know you have to use addLastfunction to add elements to the end of mylist1 by looping throughmylist2.
