Hey all, I'm using twisted in a project and have run into a class that's in version 11.1 but not 8.2 in OSX. I was thinking to get it working for mac users I could just extract the 11.1 twisted package and through it under my package. e.g. project/ __init__.py twisted/ __init__.py ...

As I understand it, with gives you a cleaner way of doing the following steps: 1) pre processing 2) actual work 3) post processing, where the __enter__ and __exit__ methods are used to take care of 1 and 3. So with is not always necessary, but it is the preferred was to do things like file proces

I'm converting some os.popen calls to use subprocess.Popen. I had previously been ignoring stdout and stderr when using os.popen. The primary motivation to switch to subprocess.Popen now is that I now want to check stderr, so would have to make code changes to use os.popen[34] anyway. Might as w
