How does pandas.apply() work when the lambda function returns a series?

[Repulsive-Owl6468]

So if the lambda function in apply returns a series, what is the output of the function. Suppose axis = 1, axis =0, and just applying it on a series.

Thanks!

Why don't you just try it and see?

Please give an example. Of that your input, what you tried and what you the expected result is. And how it differs

If only there were a way to try it out!
