Question

I need to create a CSV based on html form input. I have it working, but if someone puts a comma in one of the fields, then there will be an issue. This is very likely to happen due to the expected input. Is there a way to replace commas in the input string before it gets written to the file?

Answer 1

The best way to create CSV files with Python (including automatically dealing with this comma issue) is to use the csv standard library module. You can use this by creating a CSV writer object with

import csv
writer = csv.writer(open(filename))

Then you can actually write to the file with writer.writerow or writer.writerows

If you want the columns in your file to be named, you can use a csv.DictWriter
