In Python 3.5 or newest release

Imagine that the most of the functions that we have been using to process lists in Python do not exist. For the problems below you are not allowed to use any list methods (append, remove, insert, etc) or certain core Python functions specified in each problem. You may, however, use your own custom-written functions to solve these problems (i.e. if you find that your listlen() function would be useful in writing another function you are welcome to use it). Given these restrictions, write a series of functions that do the following:

7. Write a new function called "listreverse" based on the following IPO

# function: listreverse # INPUT: a list # PROCESSING: creates a copy of the supplied list that # contains the same elements as the original # list, but in reverse order # OUTPUT: return a new copy of the list in reverse order 

Make sure that you DO NOT use any list methods such as "reverse" your program. Note that your original list should not change when you run this function. Here is a sample running of this program:

mylist = [10, 20, 30] x = listreverse(mylist) print (x) print (mylist) >> [30, 20, 10] >> [10, 20, 30]
