Python: Tips of the Day

Returns a list of elements that exist in both lists, after applying the provided function to each list element of both.

Example:

def tips_intersection_by(a, b, fn):
  _b = set(map(fn, b))
  return [item for item in a if fn(item) in _b]

from math import floor
print(tips_intersection_by([2.1, 1.2], [2.3, 3.4],floor))

Output:

[2.1]
