Examples for Python profiling presentation, given at Montréal-Python on March 22nd, 2021.

The profilers covered were Pyinstrument, Scalene, Py-Spy, and VizTracer.

The `Makefile` shows an example or two for how to run each of these profilers.

We assume you already have a recent version of Python (say, 3.9) and

[Pipenv](https://pipenv.pypa.io/en/latest/install/#installing-pipenv) installed.

Then, in a command-line, run:

1. `pipenv install` — to install all the tools

2. `make pyinstrument` — for example, to run Pyinstrument on the sample `slow_program.py` and output its report.
