r/learnpython on Reddit: Online Python Debugger/Code Sharer
June 14, 2014 -

Hi all! I stumbled across this subreddit a few months ago, and was impressed with the scene here. Y'all seem more mature and purely want to learn/share knowledge, unlike other places that seem to get clogged up with "here's my homework do it for me" type requests. I made a mental note to come back when I got some projects of mine into stable/usable states.

I'm a programmer (big generalization) by day, and am constantly helping coworkers/friends/family/etc with programming and computer questions and concepts. Long story short, I got fed up with the available online code-sharing/debugging tools, and wrote my own. (I was also looking for an excuse to use some new technologies).

I'm rather proud of the work I did on them. Anyways, just wanted to share them and let y'all know that there's some new (and IMO better, but I'm pretty biased) tools out there for sharing/debugging code samples and helping others learn.

These are my two sites that are finally at version 1.0 (maybe still a bit beta though)

  • dbgr.cc - online code debugger/sharer - only python (my favorite) is currently supported for debugging - I'll be implementing other languages soon-ish

  • noobcoderz.com - tutorial site that uses the online debugger for code examples. I only have a general programming tutorial section and a bit of a python section up right now.

I see dbgr.cc being most useful for code sharing/debugging for r/learnpython though.

I hope they're as useful as I've imagined them to be. If not, oh well, they were fun to make.

Thanks for reading!
