I love Pycharm, and I think people who go without IDE support are masochists (I did it for a few years with Python, and I'm not going back) but it's not like the kind of tooling support you get from a proper statically typed language, where the IDE can do so much to help you.
And I say this as someone who's been full time in Python for years. It's a fun language to write, with a wonderful ecosystem, but it's not good enough when your codebase gets big or you need to do major refactoring.
It does and IMO this is the wrong approach. I usually fire off a test and use that the push the code to the line I'm interested in, at which point I fire up IPython.embed().
That gives you perfect code completion, instant variable inspection (including instant docstring and code lookup) and the ability to execute and inspect on the fly.
You can then fairly easily copy and paste the lines you want back to the text editor.
IMO that's a step ahead of just having autocomplete in an IDE.
