Often, stating your platform makes it much easier for folks here to help you.

Thank you for your reply.

This is a general question about Python. I use the 'https://glitch.com/' platform on a PC.
I have no python pocket calculator at the moment, but maybe one day.

To solve my problem, I try to add a column to the CSV file.
I get what I want if the calculation is an addition.

But no other operation is allowed… no surprise: these are strings!

If only I had a solution to convert these strings in numbers…
