Brian #1: The weird quirk with rounding in Python

• Tom Nijhof-Verheesb
• With numbers ending in .5, Python always rounds to an even number.
  • round(0.5) → 0
  • round(1.5) → 2
  • etc
• This follows IEEE 754
• You can use decimal if you need a different behavior.

Michael #2: Python interpreter adds tail calls

• Ken Jin, a member of the project, has merged a new set of changes that have been benchmarked as improving performance by 10% for some architectures.
• "Speedup is roughly equal to 2 minor CPython releases worth of improvements. For example, CPython 3.12 roughly sped up by 5%.”

Brian #3: Remove punctuation from a string with translate and maketrans

• Rodrigo
• “Don't use the method replace to remove punctuation from a Python string. Instead, use the method translate.”

Michael #4: Extra, extra, extra

• Animation v Coding, hello world to transformers
• TypeScript rewritten in Go
• Firefox lies
• PyCon’s Startup Row
• Python in Production Book
