# Exercise
|
|
# The target of this exercise is to create two lists called x_list and y_list, which contain 10 instances of the variables x and y, respectively. You are also required to create a list called big_list, which contains the variables x and y, 10 times each, by concatenating the two lists you have created.
|
|
|
|
x = object()
|
|
y = object()
|
|
|
|
# TODO: change this code
|
|
x_list = [x] * 10
|
|
y_list = [y] * 10
|
|
big_list = x_list + y_list
|
|
|
|
print("x_list contains %d objects" % len(x_list))
|
|
print("y_list contains %d objects" % len(y_list))
|
|
print("big_list contains %d objects" % len(big_list))
|
|
|
|
# testing code
|
|
if x_list.count(x) == 10 and y_list.count(y) == 10:
|
|
print("Almost there...")
|
|
if big_list.count(x) == 10 and big_list.count(y) == 10:
|
|
print("Great!") |
