Before you start this assignment, MAKE SURE you study the "Course Setup and Instructions" section of the course web page. In the Python shell, you can use the following command to view the list class public interface: dir(list) You can use the following command to view descriptions for the list class methods: help(list) Make sure you test your program each time you add the code for a given task. This is called incremental testing. It is better to find errors early so you do not repeat them. The starting contents of a data structure includes both its size and item values. The expected output is based on the starting contents of myList. I could change the starting contents of myList when I test your code. You are NOT allowed to hard-code an answer to any part. Your code should work if I change the starting contents of myList. For example, for part 1, you must NOT have: print (1) print (6) print (10) For this part, you should use list indexing to print each item. You are not allowed to re-initialization myList in any part. Your code MUST progressively modify myList as specified in the comments. Do NOT write code in any part like: myList = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10] or myList = [10, 9, 8, 7, 6, 5, 4, 3, 2, 1] or myList = anything else

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

# This program exercises Python built-in lists.
 
# Replace any "" comments with your own code statement(s)
# to accomplish the specified task.
# Do not change any other code.
 
# Here is your starting list: 
myList = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]
 
# Print the list:
print("myList:")
print(myList)
 
# Part 1:
# Print the items at indexes 0, 5, and 9:
print()
print("Items at indexes 0, 5, and 9:")
#
 
# Part 2:
# Use the len() function to print the number of items in the list:
print()
print("Length of list:")
#
 
# Part 3:
# Use the append() method to add the number 5 to the end of the list:
print()
print("Using append() to add the number 5 to the end of the list:")
#
print(myList)
 
# Print the number of items in the list:
print()
print("Length of list:")
print(len(myList))
 
# Part 4:
# Use the count() method to print the number of times
# the number 5 occurs in the list:
print()
print("Using count() to find the number of times 5 occurs in the list:")
#
# Make sure your code prints your result.
 
# Part 5:
# Use the pop() method to remove the last item from the list:
# The last item is the one at index len(myList) - 1.
print()
print("Using pop() to remove the last item from the list:")
#
print(myList)
 
# Part 6:
# Use the remove() method to remove the number 7 from the list:
# This will remove the first (and only) 7 it finds.
print()
print("Using remove() to remove the number 7 from the list:")
#
print(myList)
 
# Part 7:
# Use the insert() method to insert the number 7 back in the list:
# Insert it where it is supposed to go, which is at index 6.
print()
print("Using insert() to insert the number 7 back in the list:")
#
print(myList)
 
# Part 8:
# Use the index() method to find the index of the number 7 in the list:
# This will be for the first (and only) 7 it finds.
print()
print("Using index() to find the index of the number 7 in the list:")
#
# Make sure your code prints your result.
 
# Part 9:
# Use the min() function to find the smallest item in the list:
print()
print("Using min() to find the smallest item in the list:")
#
# Make sure your code prints your result.
 
# Part 10:
# Use the max() function to find the largest item in the list:
print()
print("Using max() to find the largest item in the list:")
#
# Make sure your code prints your result.
 
# Part 11:
# Use the "in" operation to determine whether the number 7 is in the list:
print()
print("Using \"in\" to determine whether the number 7 is in the list:")
#
# Make sure your code prints your result.
 
# Part 12:
# Use the "in" operation to determine whether the number 11 is in the list:
print()
print("Using \"in\" to determine whether the number 11 is in the list:")
#
# Make sure your code prints your result.
 
# Part 13:
# Use the following kind of "for" loop
# for x in myList:
# to print each item in the list on a separate line:
print()
print("Each item in list on a separate line:")
#
# Make sure your code prints your result.
 
# Part 14:
# Use a "for" loop to add 10 to each item in the list:
# Your "for" statement should be:
# for i in range(len(myList)):
# Inside your "for" loop you will use "i" as an index
# to reference the corresponding list item.
#
# NOTE: The following code will NOT work here.
##for x in myList:
## x += 10
# The reason is because numbers are immutable and each
# list entry itself is not changed.
# Only the x references are changed.
#
print()
print("Add 10 to each item in the list:")
#
print(myList)
 
# Part 15:
# Use a "for" loop to subtract 10 from each item in the list:
print()
print("Subtract 10 from each item in the list:")
#
print(myList)
 
# Part 16:
# Use the reverse() method to reverse the items in the list:
print()
print("Using reverse() to reverse the items in the list:")
#
print(myList)
 
# Part 17:
# Use the sort() method to sort the items in the list:
# The items are to be sorted back into their original ascending order.
print()
print("Using sort() to sort the items in the list:")
#
print(myList)
 
# Use the copy() method to create a shallow copy of the list:
# Name your copy copyList.
# Shallow copies can lead to problems when the items are mutable.
# For our list, its number items are immutable (not mutable).
print()
print("Using copy() to create a shallow copy of the list:")
copyList = myList.copy()
print(copyList)
 
# Part 18:
# Use the clear() method to remove all the items from myList:
print()
print("Using clear() to remove all the items from myList:")
#
print("myList:", myList)
print("copyList:",copyList)
 
# Part 19:
# Use the extend() method to extend myList with the contents of copyList:
print()
print("Using extend() to extend myList with the contents of copyList:")
#
print("myList:", myList)
print("copyList:",copyList)
