Python: Find the items that are parity outliers in a given list

Python List: Exercise - 236 with Solution

Write a Python program to find the items that are parity outliers in a given list.

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

Sample Solution:

Python Code:

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]
  ] 
print(find_parity_outliers([1, 2, 3, 4, 6]))  
print(find_parity_outliers([1, 2, 3, 4, 5, 6, 7]))

Sample Output:

[1, 3]
[2, 4, 6]
