    Brian #1: Writing sustainable Python scripts

    • Vincent Bernat
    • Turning a quick Python script into a maintainable bit of software.
    • Topics covered:
      • Documentation as a docstring helps future users/maintainers know what problem you are solving.
      • CLI arguments with defaults instead of hardcoded values help extend the usability of the script.
      • Logging. Including debug logging (and how to turn them on with CLI arguments), and system logging for unattended scripts.
      • Tests. Simple doctests, and pytest tests utilizing parametrize to have one test and many test cases.

    Brett #2: Static Analysis and Bandit

    Michael #3: jupyter-black

    • Black formatter for Jupyter Notebook
    • One of the big gripes I have about these online editors is their formatting (often entirely absent)
    • Then the extension provides
      • a toolbar button
      • a keyboard shortcut for reformatting the current code-cell (default: Ctrl-B)
      • a keyboard shortcut for reformatting whole code-cells (default: Ctrl-Shift-B)

    Brian #4: Report Generation workflow with papermill, jupyter, rclone, nbconvert, …

    Brett #5: Rant on time deltas

    Michael #6: How — and why — you should use Python Generators

    • by Radu Raicea
    • Generator functions allow you to declare a function that behaves like an iterator.
    • They allow programmers to make an iterator in a fast, easy, and clean way.
    • They only compute it when you ask for it. This is known as lazy evaluation.
    • If you’re not using generators, you’re missing a powerful feature
    • Often they result in simpler code than with lists and standard functions





    A good programmer is someone who always looks both ways before crossing a one-way street.

    (reminds me of another joke: Adulthood is like looking both ways before crossing the street, then getting hit by an airplane)
