21:55: For when you develop a Python script on one machine, then place it for running on another, but you didn’t generate a requirements.txt file - pipreqs1 will interrogate the import statements in all python files in the directory you specify and generate a requirements.txt file based on those import statements. Then you can pip install -r requirements.txt to make sure all your script’s requirements are met. Boom.
