The newly approved Python Enhancement Proposal 751 gives Python a standard lock file format for specifying the dependencies of projects. Here’s the what, why, and when.

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!

Human-readable and machine-generated lock file will specify what direct and indirect dependencies should be installed into a Python environment.

Writing 100k rows at a time should be fine, so I could write to the file once for each parameter combination.
