This post explains how to write to a file in Python. You'll discover how to create word files (.docx), spreadsheets (.csv), text files, and more!

Remember that a CSV file is actually just a text document with a fancy formatting. That means that you actually don’t need to use a module if you want to know how to open CSV files in Python!

For example: Connect to a large sales dataset stored in a CSV file using Power Query. Preprocess the data by filtering, cleaning, or transforming it before conducting your analysis.

For that, I have some number of parameter combinations, each of which I run 100,000 times. I'd now like to write the result of each simulation to a CSV file.
