  • It will certainly make it possible for JavaScript collections to be utilized perfectly in Python code and also the other way around– with no considerable efficiency charges.

Brian # 3: Peculiarities of Python bundle versioning

  • Seth Larson
  • Yes, we have SemVer, 1.2.3, and also CalVer, 2023.6.1, and also suffixes for beta, 1.2.3 pre1.

    • Call those callables with legitimate criteria: Clear
    • Call those callables with void criteria: Boom
