I've installed Zeal and installed the Python documentation. I can see the Python tree (among others that I've installed) in the sidebar. But searching for "python append to list" or "append to list" return 0 results. In the preferences I enabled fuzzy search, still no results.
So I turned to the tree to see how easy it would be able to find the answer. I opened the Python leaf, and from the 15 subleaves I opened Structures. In there I see "PyCompilerFlags", "_frozen", and "_inittab".
I'll be sticking to Google, unfortunately.
