Kdevelop with kdev-python plugin vs Light Table

Kdevelop has very unique syntax highlighting. It's very addicting - other IDE will soon look monochrome to you.

Kdevelop indices all your classes, methods, functions and global variables in memory, which makes class/method lookups to complete in no time.

Even quite large projects occupy only several hundreds megabytes of RAM. Try that in Eclipse...

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.
