Returning multiple dataframes with Python

Question

So I want to write a function that looks something like this:

def return_all_tables(parameter):
    a_table = a(parameter)
    b_table = b(parameter)
    c_table = c(parameter)
    ...

Here, a, b and c are all different functions returning the dataframes a_table, b_table and c_table respectively.

What I'm not sure now is how to write the return statement to make it return the content of every dataframe.

a return statement doesn't display anything. Do you mean "return the content of all the dataframes"? — Marcus Müller

Edited your question to reflect that (you could have done that yourself!). Anyway, what's wrong with return (a_table, b_table, c_table)? — Marcus Müller

It just returns a list saying (<DataFrame object>, <DataFrame object>, <DataFrame object>), but I want the function to display what's in these respective dataframes simultaneously. — Vuotelin

that's exactly what I asked when you said you didn't want to display... — Marcus Müller

You would want something like this

def return_all_tables(parameter):
    a_table = a(parameter)
    b_table = b(parameter)
    c_table = c(parameter)
    return a_table, b_table, c_table

a, b, c = return_all_tables(parameter)
display(a, b, c)

return a_table, b_table, c_table will return a 3-tuple containing the dataframes.
