Unnecessary underscores in the documentation

Report

It is not uncommon to see elements of code like this in the documentation:

_ = ep.tl.causal_inference(
    adata=adata,
    graph=causal_graph,
    treatment="aline_flg",
    outcome="icu_los_day",
    estimation_method="backdoor.linear_regression",
)

What is the point of having _ = ? This is exactly what happens in Python internally, anyway. If this is done to prevent printing an output returned by the function, a much more elegant way would be to put ; at the end of the line.

I'm pretty sure I asked this question already, but probably not on GitHub. Sorry for not remembering the answer

Version information

The current release of ehrapy at the time of writing is 0.8.0

Yeah, this is totally not elegant.

There is a third option which is to tag the cell with hide-output which is interpreted by most sphinx themes.

Will be fixed!

Thank you.
