Step 1: Program

A required Python program is as follows,

File name: “threeLists.py”

# a)List comprehension of multiples of 4 from 0 to 10

list_1 = [j*4 for j in range(11) ]

# b)Print the list

print(list_1)

# c)Create a second empty list

list_2=[]

# d) Use loop

for j in list_1:

    ''' Insert all the elements from first list to

    second list. Before storing divide each copied element by 2'''

    list_2.append(j//2)

# e)Print the second list

print(list_2)

# f) Use slicing to copy the second list to a third list

list_3=list_2[:]

# g) Use a loop

for j in range(len(list_3)):

    #Divide and store each element of third list by 2

    list_3[j]=list_3[j]//2

# h) Print the third list

print(list_3)
