Python: Tips of the Day

Maps the values of a list to a dictionary using a function, where the key-value pairs consist of the original value as the key and the result of the function as the value:


def tips_map_dictionary(itr, fn):
  ret = {}
  for a in itr:
    ret[a] = fn(a)
  return ret
print(tips_map_dictionary([2,4,6], lambda a: a * a))


{2: 4, 4: 16, 6: 36}
