No list comprehension? I thought list comprehension were faster than loops?

  Yes but it's still a loop in Python, which means it calls iter() then __next__() in a try/except to catch StopIteration in the end. It's a lot of overhead. tostring() or encode() will do an implicity loop in C, which will be much faster.

  List comprehensions didn't exist when this post was written.

    Python 2.0, back in 2000, had them.

      The last sentence (grep for "since this essay was written") suggests that the article was written before the 'B' typecode was added to the array module. This typecode was added in Python 1.5.

  Usually a little slower, when I've timed them. (This may be out of date.) in Py3 they byte-compile into a loop in a nested function.
