Python Lock Files Become Tool-Agnostic with PEP 751
Real Python
EDITOR BRIEF
PEP 751 standardizes Python lock files with a new pylock.toml format. The excerpt says you can create one with pip or uv, then install from it with uv or pdm, as a replacement for requirements.txt.
INSIGHTS
This matters because lock files help keep installs consistent across machines. If you’re learning Python packaging, try comparing requirements.txt with pylock.toml and testing how different tools read the same lock file.
