Kdevelop with kdev-python vs Light Table

PyCharm is amazing and easily the most feature option out there. But KDevelop is faster and has all the features needed for python develop. Opening new files, moving from file to file, code and syntax checks, everything happens instantly.
In the end the speed is what won me over to use KDevelop, when code is in my mind I don't want to wait on my IDE.

Kdevelop has very smart syntax and semantic syntax highlighting.

Kdevelop has a pretty powerful and sophisticated implementation of static analysis for Python. It's capable of pretty good type inference, tracking types and the expected groking of inheritance trees.

Most IDEs have very limited vim bindings, but KDevelop runs on the Kate editor. Kate is one of the most robust editors in the Linux world and is subsequently very functional. The Vim bindings are very close to complete with very few holes.

With LT's inline evaluation, you don't have to re-compile your whole source file. Each time you want to see an output, all you have to do is hover your cursor over the line you'd like to evaluate and press ctrl+enter; LT will evaluate that line of code for you.

The "Watches" feature lets you see your code running live as you type it. This means that you can debug your code live while writing it, which leads to considerably less programming errors.

LT has a plugin manager built directly inside of it. This plugin manager connects to LT's own registry of plugins, so whenever you want assistance while writing your HTML, JS, or even Python, just open up the plugin manager, search for it, and click the little install button beside it's name. Your plugin will then be installed.
