# 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 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:") #
# 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:") #
# 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:") #
