I've had much success doing round trips through the lxml.html parser.

I ditched bs for lxml long ago and never regretted it.
If you find that you have a bunch of invalid html that lxml inadvertently
"fixes", I would recommend adding a stutter-step to your project: p

It used to be that the best way to compare floating point numbers while

I'm trying to work through Skienna's algorithms handbook, and note that the
author often uses graphical representations of the diagrams to help understand
(and even debug) the algorithms. I'd like to reproduce this in python.
How would you go about this? pyQt, pygame and pyglet immediately come

Latin1 has a block of 32 undefined characters.
Windows-1252 (aka cp1252) fills in 27 of these characters but leaves five
undefined: 0x81, 0x8D, 0x8F, 0x90, 0x9D
The byte 0x81 decoded with latin gives the unicode 0x81.
Decoding the same byte with windows-1252 yields a stack trace with
`UnicodeDec

I feel like the design of sum() is inconsistent with other language
features of python. Often python doesn't require a specific type, only
that the type implement certain methods.

I'd like to get to zero-installation if possible. It's easy with
