Anybody think that this may actually be a mistake in the Python docs? Who
would I contact about getting them corrected?

The "is" operator just shows the effect of this caching. It's

Hi all,
I've got a very simple HTML proxy server to access the web from my

It's a very retarded phone that freezes if there's no Content-Length
header and some other circumstances, so I have to tweak and modify the
headers

They're usually stored in something like /usr/lib/python2.4

Good point! Perl has more characters than Python, and I find they make
it harder to read because they are distracting.

Yep, use regular expressions! For example, use the regular expression

One other thing I'm wondering: how exactly does Tkinter work? Is the
whole Tk toolkit bound up as library of low-level C code, or does
Tkinter sit on top of a Tcl interpreter?
If the latter, that might explain why it is frustratingly slow on
Cygwin... since Cygwin is not very good at starting up

n quickly move programs to new measurement computers. I like GTK a
lot and Tk is growing on me too.. are there any higher-level "wrapper"
toolkits for GTK and Tk?
Thanks for any advice!
