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
