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 @Alberto de Santos, 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.
