Re: [Tutor] I love python / you guys :)
Stefan, you echoed my thinking too :) On Mon, Nov 16, 2009 at 8:58 AM, Stefan Lesicnik ste...@lsd.co.za wrote: hi, Although not a question, i just want to tell you guys how awesome you are!

I really appreciate all the effort the knowledgeable guys put into this list (you know who you are! you post answers all the time!). I've asked a couple of questions and the answers have always been excellent and i've learnt so much. So i guess i just wanted to say thanks for supporting a great language, and helping me as i learn to shape my thinking into better and better ways to do things. stefan ___ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: http://mail.python.org/mailman/listinfo/tutor -- Regards, Lloyd ___ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: http://mail.python.org/mailman/listinfo/tutor

Hi Stefan, Your message mirrored my current state. There's TONS to learn in linux like bash, perl, vim, sed, awk, python, etc. Too much to put in your head and in the end makes you half-baked e.g. good at start but fades away in the end. Anyway i hope to follow your lead and be one among the guys here knowledgeable of the language. In the same lines of if-you-can-think-of-anything-python-can-do-it i got inspired to ask a question for the gurus: When i use our company's LAN i set my proxy variable by hand in .bashrc. There are 4 files to insert proxy variable: in ~/.bashrc, /root/.bashrc, /etc/wgetrc and /etc/apt/apt.conf. The last one is actually rename e.g. mv to apt.conf to activate proxy and mv to apt.conf.bak to deactivate. The proxy variable is something like this export http_proxy=http://username:passw...@proxy:port ftp_proxy=$http_proxy To activate i uncomment them then source .bashrc. To deactivate i put back the comment sign. I do it all in vim e.g. vim -o the-3-files-above. For apt.conf see rename above. I deactivate because i have another internet connection option via 3G usb modem. But thats another story. I will do this myself in python so please show me the way. Surely this can be done. -- Best Regards, bibimidi ___ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: http://mail.python.org/mailman/listinfo/tutor

Sure it can.
This is actually fairly easy to do. I would just use regular expressions to
match the lines and comment/uncomment them depending on if you want to
enable/disable.
Spoiler alert! don't read if you want to solve it yourself.
Remove/Add comments to any line that matches a specified regular
expression.
##comments are assumed to be the '#' symbol.
Warning - completely untested code.
import re
regex = # remove leading spaces and the # comment symbol from a line, if it
exists.
def uncomment(filename, regex, newfile):
remove_comments_regex = ' *#*(.*$)'
for line in open(filename):
if re.match(regex, line): # if we have a matching line we should
remove the comment.
newfile.write(re.match(remove_comments_regex, line).groups()[0])
def comment(filename, regex, newfile):
for line in open(filename):
if re.match(regex, line):
#avoid dual-commenting
if line.strip().startswith(#):
newfile.write(line)
else:
newfile.write('#' + line)
End of spoiler
As for renaming, look into the os module, there's an easy function for
renaming in there. Just add a check around the rename function for an
os.path.exists(...) so you can ensure the file exists before you attempt to
rename it, otherwise you might get an exception (or you could just try
renaming it and just catch the exception, either way.) Then just make a
.py script that can enable and one that can disable, and make sure tehre's
no harm if you run either one multiple times consecutively.
Hope that helps, and yes, we know you guys appreciate the help, that's why
we do it! We certainly don't get paid anything. It's nice to hear you say
it anyway though, so thanks!

I've always found it to be full of invaluable advice, and is, in my opinion, a real gem in Python's crown. It's one of the reasons I feel so confident in recommending python to anyone - they can be guaranteed a friendly and informational welcome on this list. Thank you very much - it is greatly appreciated. S. ___ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: http://mail.python.org/mailman/listinfo/tutor
