A suggestion for improving the documentation of chapter 10.9. Data Compression
by Guy Goldner 22 May '24

22 May '24

Hello dear Python gods :) I'm new at Python and was going over the documentation . This useful paragraph : https://docs.python.org/3.7/tutorial/stdlib.html#data-compression provides info for compressing text but IMHO some important additional info is needed, without which I expect nearly all users would get stuck just as I have. Moreover, while looking for a solution I noticed a lot of articles with outdated examples which no longer work - this confused me even more to the point I started suspecting something was amiss on my end... Anyhow, adding this info would do the trick : zlib works only with bytes and in Python 3.x strings are no longer bytes. Example : *>>> zlib.compress('this is a sample string which does not work in zlib because it requires bytes and not unicode')Traceback (most recent call last): File "<stdin>", line 1, in <module>TypeError: a bytes-like object is required, not 'str'>>>* Luckily Python has a very simple solution for this : encode to utf-8, compress, decode back to unicode like so : *>>> text = 'this is a sample string which does not work in zlib because it requires bytes and not unicode with chars like this »שלום '>>> encoded = text.encode()>>> text = 'this is a sample with unicode chars »שלום '>>> encoded = text.encode()>>> compressed = zlib.compress(encoded)>>> decompressed = zlib.decompress(compressed)>>> decoded = decompressed.decode()>>> len(text),len(encoded),len(compressed) #notice that compression of short strings can be larger than the original(42, 47, 54)>>> print(text,'\n',encoded,'\n',compressed)this is a sample with unicode chars »שלום b'this is a sample with unicode chars \xc2\xbb\xd7\xa9\xd7\x9c\xd7\x95\xd7\x9d ' b'x\x9c+\xc9\xc8,V\x00\xa2D\x85\xe2\xc4\xdc\x82\x9cT\x85\xf2\xcc\x92\x0c\x85\xd2\xbc\xcc\xe4\xfc\x94T\x85\xe4\x8c\xc4\xa2b\x85C\xbb\xaf\xaf\xbc>\xe7\xfa\xd4\xebs\x15\x00\xb2K\x14|'>>> text == decodedTrue* Thank you ! You are doing a great thing ! B.R., Guy Goldner

Documentation by Version Not Downloadable
by Julian Fortune 23 Mar '23

Hey wonderful python docs maintainers, I noticed that from the Python Documentation by Version page <https://www.python.org/doc/versions/> if I navigate to a specific version of documentation—even a stable version—, e.g., `3.10.9`, when I go to *Download these documents* all the download links result in a 404 error. Example: https://docs.python.org/ftp/python/doc/3.10.9/python-3.10.9-docs-pdf-letter… *404 — Archive Not Found* > The archive you're trying to download has not been built yet. > Please try again later. Happy holidays and New Year; Thanks! Julian

Raw String Bug?
by garfield＠garfieldhudson.com 07 Mar '23

Hi guys, Is this a bug with raw strings? If the last character of the string is a backslash, I get an unterminated string error. If I add another character, the error goes away. I thought that the r prefix rendered everything within the quotes as literals. Thanks, Garfield.
