text = ['aaaa', 'bb', 'ccc ccc'] length_1 = map(lambda x: len(x), text) print(length_1) # <map object at 0x7f60ceb90f98> print(list(length_1)) # [4, 2, 7] length_2 = map(len, text) print(length_2) # <map object at 0x7f60ceb90fd0> print(list(length_2)) # [4, 2, 7] length_3 = [ len(s) for s in text ] print(length_3) # [4, 2, 7]
In LISP this would be a mapcar.
