Specs
Question Ranking
Pros
Pro Real-time static analysis
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.
Pro Excellent syntax highlighting
Kdevelop has very smart syntax and semantic syntax highlighting.
Pro Blazingly Fast
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.
Pro Best Vim Bindings in an IDE
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.
Pro Lightweight
PyScripter is a lightweight Python IDE.
Pro Easy to use
Covers the needs of advanced users (thread debugging, unit testing etc.)
Cons
