Just created a short presentation for work about why I’m checking out the PyCharm IDE.
I wrote an article about trying out PyCharm for Python development. I learned to use it when working with Django (though I have used Emacs for web development usually). PyCharm has a lot of advantages and what I like about it, and RubyMine, is that you can use Ctrl+Click (on GNU/Linux and Windows) or Command+Click (on Mac OS X) to see where a method or class is defined or to find where it is being used in the code base.
Update: found a nice post by a VIM user who switched to PyCharm and found it awesome how integrated everything is.
