I have already created some of the code for this. my current issue is getting the lines of code for main() correct. as per my professors instruction. I can and will post any codes I have worked on if necessary. Create a python file list_copy.py and add define function named listcopy(sourceList) Write code to create an empty list named retList, loop through the items in sourceList and appending retList. The function should return retList Add a main() function and an entry point for your program. In the main create a list named list1 and print(list1), create list2 = listcopy(list1) and print list2. Test if both lists are equal
