Sorry, can you elaborate I don;t understand what you mean?
The data you show does not seem to be related to the output
you show?

Also having the city be a dual name separated by a comma
within a csv file is likely to create confusion, not least
for yourself. I would suggest splitting it to city and
country. If that doesn't work (for your API perhaps)
then consider changing the separator.  If that doesn't
work for you then tough luck, you'll need to persevere.

You import csv but don't seem to use it anywhere below?

Again this does not seem to match either the the
data sample shown above or the output.

This will produce something like the output you showed
(although I don't think you need all the str() calls).
But it is nothing like the output you said you wanted
in the csv file and you are not using csv anywhere
to generate it.

What exactly are you asking us to help you with?
Everything seems to be doing exactly what you are
asking it to do.
