Deep dives

Introduction of Pyrel Tool

A new tool called Pyrel has been introduced, providing users easy access to Python's release cycle information. By using commands like 'Pyrel check', developers can quickly ascertain the maintenance status of their current Python version, including whether it is actively maintained or has reached end-of-life status. Additionally, 'Pyrel list' offers a summary of the last ten versions with their respective release and end-of-life dates. This functionality allows developers to better manage their Python environments and stay informed about necessary upgrades.

Michael #1: pirel: Python release cycle in your terminal

pirel check shows release information about your active Python interpreter.
If the active version is end-of-life, the program exits with code 1. If no active Python interpreter is found, the program exits with code 2.
pirel list lists all Python releases in a table. Your active Python interpreter is highlighted.

Brian #2: FastAPI Cloud

Sebastián Ramírez, creator of FastAPI, announced today the formation of a new Company, FastAPI Cloud.
Here’s the announcement blog post: FastAPI Cloud - By The Same Team Behind FastAPI
There’s a wait list to try it out.
Promises to turns deployment into fastapi login; fastapi deploy
Side note: announcement includes quote from Daft Punk: Build Harder, Better, Faster, Stronger
- I just included this in a talk I’m gave last week (and will again next week), where I modify this to “Build Easier, Better, Faster, Stronger”
- Sebastian and I are both fans of the rocket emoji.
BTW, we first covered FastAPI on episode 123 in 2019

Brian #3: Python's new t-strings

Dave Peck, one of the authors of PEP 750, which will go into Python 3.14
We covered t-strings in ep 428
In article
- t-strings security benefits over f-strings
- How to work with t-strings
- A Pig Latin example
  - Also, I think I have always done this wrong
  - Is it the first consonant to the end? or the first consonant cluster?
  - So… Brian → Rianbay? or Ianbray?
  - BTW, this is an example of nerdgassing
- What’s next once t-strings ship?
On thing that’s next (in Python 3.15, maybe, is using t-strings in shlex and subprocess)
- PEP 787 – Safer subprocess usage using t-strings deferred to 3.15

Michael #4: zev

A simple CLI tool to help you remember terminal commands.

Examples:

# Find running processes
zev 'show all running python processes'
# File operations
zev 'find all .py files modified in the last 24 hours'
# System information
zev 'show disk usage for current directory'
# Network commands
zev 'check if google.com is reachable'
# Git operations
zev 'show uncommitted changes in git'
