-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi, First of all, thanks for maintaining great documentation! I use it constantly, and it is very well written and easy to understand. I spotted a bug in the gzip documentation for 3.1.2. At the bottom of the page http://docs.python.org/py3k/library/gzip.html, section 12.2.1. Examples of usage, we read the following: import gzip content = "Lots of content here" f = gzip.open('/home/joe/file.txt.gz', 'wb') f.write(content) f.close() Running this example fails, as shown below: (default)Micron:py3k-1.2 loic$ python3 Python 3.1.2 (r312:79147, Jul 18 2010, 02:49:37) [GCC 4.2.1 (Apple Inc. build 5659)] on darwin Type "help", "copyright", "credits" or "license" for more information. line 226, in write self.crc = zlib.crc32(data, self.crc) & 0xffffffff TypeError: must be bytes or buffer, not str

The solution (which I found thanks to Google and diveintopython3.org) is to change the fourth line in the example: import gzip content = "Lots of content here" f = gzip.open('/home/joe/file.txt.gz', 'wb') f.write(content.encode('utf-8')) f.close() I haven't check the last example on that webpage, but I think it has the same problem. Hope this helps, Loïc -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.10 (Darwin) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iEYEARECAAYFAkxGXuEACgkQLKWiTxa2C806jQCgwRShTRSnJJwNyoZHwbckgYKe wrcAnAuFkm1vI1X3FabP/I5btw9IhGMr =kMgZ -----END PGP SIGNATURE-----
