Brian #1: Python's Missing Batteries: Essential Libraries You're Missing Out On

• Martin Heinz
• Fun collection of a bunch of libraries you may not know about (or forgot about), with code examples.
• Utilities
  • boltons : iterate through json and dates, quickly grab data out of nested structures, and convert nested data with jsonutils, timeutils, and iterutils
  • sh : conveniently call shell funcitons
• Data Validation
  • validators : validate email addresses, credit cars, IP addresses, and more.
  • the fuzz : fuzzy string comparisons
• Debugging
  • stackprinter : nice stack traces with exception messages higlighted
• Testing
  • freezegun : stop time, change dates, …
  • dirty_equals : comparing things that are kinda equal
• CLI
  • tqdm : add a progress bar to command line apps

Michael #2: awesome-polars

• A curated list of Polars talks, tools, examples & articles.
• Mostly articles and tutorials however.

Brian #3: Running Headless Selenium in Python (2023)

• Siddiqi
• First off, if you are doing automated testing with Selenium, I hope you already know about headless. It’s awesome and speeds up testing.
• Next, there’s changes to how you code headless, as of Selenium 4.8.0 (Jan. 2023).
• Old:
  • options.headless` `**=**` `True
• New:
  • options.add_argument('--headless=new') for Chrome
  • options.add_argument('--headless') for Firefox
• Reasons: Read Headless is Going Away! post on Selenium blog.
  • Subtitle: “Now that we got your attention, headless is not actually going away, just the convenience method to set it in Selenium”

Michael #4: Gracy

• Gracy helps you handle failures, logging, retries, throttling, and tracking for all your HTTP interactions.

• Has support for

  • Parsing per status code
  • Throttling
  • Retries
  • Custom validation
  • Record/replay for testing

• A bit non-pythonic but perhaps inspriation for some out there

Extras

Michael:

• Mobile apps are finally out
  • Take the git course for free for a limited time.
