Using Flask To Return Multiple Dataframes As Csv

I've multiple dataframes and i want to return multiple downloadable CSV files using flask. I tried following code but it can only return one downloadable CSV file. resp = make_resp

Solution 1:

I got my answer, Actually there is no way to return all files at once using flask only so i made a zip file containing all CSVs and then returned it.

import zipfile

with zipfile.ZipFile('main_code/output.zip', 'w') as csv_zip:
    csv_zip.writestr("data1.csv", data1.to_csv())
    csv_zip.writestr("data2.csv", data2.to_csv())

return send_file('output.zip',
                 mimetype='zip',
                 attachment_filename='output.zip',
                 as_attachment=True)
