I've been using Eclipse PyDev, which can show you the source code snippet of an object or a function when your mouse hovers over it.
I'm aware that PyCharm can show a quick documentation snippet on hover: How can I make docstrings popup on hover in PyCharm?
However, the ability to hover and peek at the source code is very important to my workflow. I wonder whether there's a built-in way or a plugin to achieve this?
