Introduction
In this challenge, you are tasked with finding the parity outliers in a given list. Parity outliers are elements in a list that have a different parity (odd or even) than the majority of the elements in the list.
In this challenge, you are tasked with finding the parity outliers in a given list. Parity outliers are elements in a list that have a different parity (odd or even) than the majority of the elements in the list.
Write a function find_parity_outliers(nums)
that takes a list of integers nums
as an argument and returns a list of all the parity outliers in nums
.
To solve this problem, you can follow these steps:
collections.Counter
with a list comprehension to count even and odd values in the list.collections.Counter.most_common()
to get the most common parity.from collections import Counter
def find_parity_outliers(nums):
return [
x for x in nums
if x % 2 != Counter([n % 2 for n in nums]).most_common()[0][0]
]
find_parity_outliers([1, 2, 3, 4, 6]) ## [1, 3]
In this challenge, you learned how to find the parity outliers in a list of integers. You used the collections.Counter
module to count even and odd values in the list, and then found the most common parity. Finally, you used a list comprehension to find all elements that do not match the most common parity.
