Question

Use Python.

Let a be the list of values produced by range(1, 11).

a). Using the function map with a lambda argument, write an expression that will produce
each of the following:

i) A list of cubic of the corresponding values in the original list; The expected output
should be a list as follows,

[1, 8, 27, 64, 125, 216, 343, 512, 729, 1000]

ii) A list where each element is larger by one than the corresponding element in the
original list; The expected output should be a list as follows,

[2, 3, 4, 5, 6, 7, 8, 9, 10, 11]

b) Write a list comprehension that will produce each of the following:

i)  A list contains values in the original list that are less than or equal to 5; The
expected output should be a list as follows,

[1, 2, 3, 4, 5]

ii) A list contains values that are the square of odd values in the original list. The
expected output should be a list as follows,

[1, 9, 25, 49, 81]

Answer 1

# Let a be the list of values produced by range(1, 11).
a = list(range(1, 11))
# a). Using the function map with a lambda argument, write an expression that will produce
# each of the following:
#
# i) A list of cubic of the corresponding values in the original list; The expected output
# should be a list as follows,
print(list(map(lambda x: x ** 3, a)))
# [1, 8, 27, 64, 125, 216, 343, 512, 729, 1000]
#
# ii) A list where each element is larger by one than the corresponding element in the
# original list; The expected output should be a list as follows,
print(list(map(lambda x: x + 1, a)))
# [2, 3, 4, 5, 6, 7, 8, 9, 10, 11]
#
# b) Write a list comprehension that will produce each of the following:
#
# i)  A list contains values in the original list that are less than or equal to 5; The
# expected output should be a list as follows,
print([x for x in a if x <= 5])
# [1, 2, 3, 4, 5]
#
# ii) A list contains values that are the square of odd values in the original list. The
# expected output should be a list as follows,
print([x * x for x in a if x % 2 == 1])
# [1, 9, 25, 49, 81]
