Python Question

Use python requests to download CSV

Here is my code:

import csv
import requests
with requests.Session() as s:, data=payload)
download = s.get('url that directly download a csv report')

This gives me the access to the csv file. I tried different method to deal with the download:

This will give the the csv file in one string:

print download.content

This print the first row and return error: _csv.Error: new-line character seen in unquoted field

cr = csv.reader(download, dialect=csv.excel_tab)
for row in cr:
print row

This will print a letter in each row and it won't print the whole thing:

cr = csv.reader(download.content, dialect=csv.excel_tab)
for row in cr:
print row

My question is what is what's the most efficient way to read a csv file in this situation.
And how to download the actual csv file.

This should help:

from __future__ import print_function

import csv
import requests

CSV_URL = ''

with requests.Session() as s:
    download = s.get(CSV_URL)

    decoded_content = download.content.decode('utf-8')

    cr = csv.reader(decoded_content.splitlines(), delimiter=',')
    my_list = list(cr)
    for row in my_list:
