python - iPython Code Completion / Intellisense on Dot Possible?

Question

As someone trying to learn the ins and outs of Python (with emphasis on scientific computing - ie: pandas, numpy, scikit-learn), most of the gurus out there seem to recommend and use iPython notebooks. My biggest sticking point as a beginner/intermediate coder is that I NEED code completion / intellisense -like functionality from an IDE to learn the function parameters. I'm not hard-wired yet to just know what parameters are available at my current development.

In iPython, I noticed I can press Tab to show the drop-down of options (seen below as pd.) but I don't want to have to hit each time. That's not user-friendly for my needs. Instead, I would like it to show only available classes and methods when I press dot.

Secondly, I notice that if I did say pd.read_csv(<TAB>, I get a lot more options than are the actual parameters in read_csv.

Question: Can iPython automatically show accurate code completion options instantly after pressing dot / period? Also, is there a way to configure it to only show the available function parameters when within a function?

To make this question super-specific, I'm not asking about using any other IDE; I'm asking very specifically in regards to just iPython and wondering if there's a way to set some kind of configuration to achieve accurate "dot" display options instantly when pressing "dot" (no time delay).

Example below shows Desktop which is obviously not a parameter of pd.read_csv().

You can press <Shift>-<Tab> to get a tooltip showing the function's signature:

Alternatively, invoking zip? opens a documentation pane at the bottom of the window.

As far as having the tooltip open automatically, I'm unsure. I'd guess that it isn't possible via configuration.
