Returns True if the provided function returns True for at least one element in the list, False otherwise.

Iterate over the elements of the list to test if every element in the list returns True based on fn. Omit the seconds argument, fn, to check if all elements are True.

def some(lst, fn=lambda x: not not x):
  for el in lst:
    if fn(el):
      return True
  return False

some([0, 1, 2, 0], lambda x: x >= 2 ) # True
some([0, 0, 1, 0]) # True
