11, which is what I expected. But I changed the byte value to 16 (because I
was having trouble getting single digit hex values working in the command) and
sent this command:

Can someone explain to me why I can't set the charset after the fact and still
have it work.
For example:
>>> text = MIMEText('❤¥'.encode('utf-8'), 'html')
>>> text.set_charset('utf-8')
>>> text.as_string()
Traceback (most recent call last):
File "", line 1, in

I think learning a language from the documentation is an unreasonable
expectation and burden for the authors.
Buy a book, take a class, they are designed to provide you with a path from
start to finish in a sensible manner, the documentation in my opinion is
supposed to be a reference and a ref
After a fair amount of troubleshooting of why my lists were coming
back a handful of digits short, and the last digit rounded off, I
determined the str() function was to blame:

I'm trying to write a script that will parse IRC chat logs and color
code them if it finds certain characters. I was able to make this
work with one character, but to make it even more accurate I would
like to use two identifying characters. Here is my code :
import urllib2
response = urllib2.u
I took this script:

when I try to resume a downloaded file, but if the file is already
downloaded, and I expect to see the print "File already downloaded"

I am using the xml.sax package, and I'm running into a little

parses, but the problem is I don't know
