What is the list comprehension equivalent for:
list(map(lambda x:x**-1, [1, 2, 3]))?
a) [1|x for x in [1, 2, 3]]
b) [-1**x for x in [1, 2, 3]]
c) [x**-1 for x in [1, 2, 3]]
d) [x^-1 for x in range(4)]
Answer: c
Explanation: The output of the function list(map(lambda x:x**-1, [1, 2, 3])) is [1.0, 0.5, 0.3333333333333333] and that of the list comprehension [x**-1 for x in [1, 2, 3]] is [1.0, 0.5, 0.3333333333333333]. Hence the answer is: [x**-1 for x in [1, 2, 3]].
