# Replace with your name.

# 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 $=[1,2,3,4,5,6,7,8,9,10,11,12]$

# Print the list:

print$("$myList:$")$

print$($myList$)$

# Part $1$:

# Print the items at indexes $0,6,$ and $11$:

print$()$

print$("$Items at indexes $0,6,$ and $11$:$")$

print$($myList$[0],$myList$[6],$myList$[11])$

# Part $2$:

# Use the len$()$ function to print the number of items in the list:

print$()$

print$("$Length of list:"$)$

print$($len$($myList$))$

# Part $3$:

# Use the append$()$ method to add the number $7$ to the end of the list:

print$()$

print$("$Using append$()$ to add the number $7$ to the end of the list:"$)$

myList.append$(7)$

print$($myList$)$

# Print the number of items in the list:

print$()$

# Part $4$:

# Use the count$()$ method to print the number of times

# the number $7$ occurs in the list:

print$()$

print$("$Using count$()$ to find the number of times $7$ occurs in the list:"$)$

print$($myList$.$count$(7))$

# 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:"$)$

myList.pop$()$

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:"$)$

myList.remove$(7)$

# 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$()$

to print each item in the list on a separate line:

print$()$

print$("$Each item in list on a separate line:"$)$

# Part $14$:

# Use a "for" loop to add $100$ to each item in the list:

# Your "for" statement should be:

for i in range$($len$($myList$))$:

# to reference the corresponding list item.

#

# NOTE: The following code will NOT work here.

# for x in myList:

# x $+=100$

# The reason is because numbers are immutable and each

# list entry itself is not changed.

# Only the x references are changed.

# Part $16$:

# Use the reverse$()$ method to reverse the items in the list:

print$()$

# 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$).$
