Sorry if my writing is a bit incoherent. ...
So earlier this year I manually built 2.6.4 for Snow Leopard because I wanted a slightly more updated version of Python than what Apple released. This has caused all kinds of problems when installing some eggs like PIL and running other 3rd party python apps. Now I just want to revert everything back to what Snow Leopard ships with becau...

I love WPF bindings, but I often find myself wish I could do a little more. PyBindings seem like a good start, but the Python syntax seems very clunky and out of place in a XAML file. Are there any alternatives out there? Something with a simpler syntax, that allows for quick comparisons & conversions so that I don't have to write (an...
