Find Parity Outliers

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.

Find Parity Outliers

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:

1. Use collections.Counter with a list comprehension to count even and odd values in the list.
2. Use collections.Counter.most_common() to get the most common parity.
3. Use a list comprehension to find all elements that do not match 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]

Summary

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.
