I am wondering how to make a `map` over a `DataFrame` , do you have any idea? I see very clear how to make it over a `list`. To my mind, it seems straightforward to convert the `DataFrame` into a `list` . So, I would like to know your opinion.

Hi <@U01C4F9T88P>, can you give us a little more context about what you want to do?

What do you mean by “make a `map`over a `DataFrame`”?  There is a function `DataFrame.applymap` which applies a function to every element in a `DataFrame` if that helps?

If you mean spawning a mapped task for each `DataFrame`  row, your upstream task can return a list of rows, and you can map over that:
`return list(df.iterrows())`

This is exactly what I wanted `iterrows()`
I am aware that `DataFrame` has an `apply` method, but not usable from a `Task` perspective.
