Find parity outliers
Finds 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.
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]
