What you are looking for is imap(). In Python 2 there are entire collection of iterator variants. You can choose to use either the list or the iterator variants. The problem with Python 3 is the list version is removed. You are forced to use iterator all the time. Things become inconvenient and ugly as a result. Bugs are regularly introduced because I forget to apply list(). >>> "".join(map(lambda byte: chr(byte), b'abc')) Compares to ''.join('abc'), this is what I call fuck'd. Luckily maxerickson suggested a better method.
