New submission from Jose-Luis Fernandez-Barros jlfbarros@gmail.com:

On "The Python Tutorial", section 10.9. Data Compression http://docs.python.org/py3k/tutorial/stdlib.html#data-compression

...

...

import zlib s = 'witch which has which witches wrist watch'

...

...

...

t = zlib.compress(s)

Traceback (most recent call last): File "<stdin>", line 1, in <module> TypeError: must be bytes or buffer, not str

Possible solution (sorry, newbie) are:

...

...

s = b'witch which has which witches wrist watch'

or

...

...

s = 'witch which has which witches wrist watch'.encode("utf-8")

At "The Python Standard Library", secction 12. Data Compression and Archiving http://docs.python.org/py3k/library/zlib.html#module-zlib apparently example is correct: zlib.compress(string[, level])
