Brian #1: zipapp

• Part of standard library since 3.5
• Yet another thing I learned recently from Brett Cannon
• “This module provides tools to manage the creation of zip files containing Python code, which can be executed directly by the Python interpreter. The module provides both a Command-Line Interface and a Python API.”
• Including: Creating Standalone Applications with zipapp

Michael #2: Reverse engineering the Apple News app with #python and #nerd power

• As we navigate the digital world, we often come across articles we don't have time to read but still want to save for later.
• One way to accomplish this is by using the Read Later feature in Apple News.
• But what if you want to access those articles outside the Apple News app, such as on a different device or with someone who doesn't use Apple News?
• Or what if you want to automatically post links to those articles on your blog? That's where the nerd powers come in.
• The linked article shows how to use Python to solve your own problem
• Leading to Rhet Turnbull’s CLI: apple-news-to-sqlite

Brian #3: What is a context manager?

• Trey Hunner
• Also look at all the cool goodies in contextlib from standard library
  • @contextmanager
  • closing
  • suppress
  • redirect_stdout, redirect_stderr
  • chdir

Michael #4: nox-poetry: Use Poetry inside Nox sessions

• via 2 people: John Hagen and Marc Prewitt
• This package provides a drop-in replacement for the nox.session decorator, and for the nox.Session object passed to user-defined session functions.
• Comes from Claudio Jolowicz's hypermodern python cookiecutter
  • Covered this on Talk Python: talkpython.fm/episodes/show/362/hypermodern-python-projects
• This session performs the following steps:
  • Build a wheel from the local package.
  • Install the wheel as well as the pytest package.
  • Invoke pytest to run the test suite against the installation.
• Consider what would happen in this session if we had imported @session from nox instead of nox_poetry:
  • Package dependencies would only be constrained by the wheel metadata, not by the lock file. In other words, their versions would not be pinned.
  • The pytest dependency would not be constrained at all.
  • Poetry would be installed as a build backend every time.
