This PR fixes incorrect documentation for
PYTHONDONTWRITEBYTECODE.The documentation previously stated that setting the variable to any
non-empty string disables writing
.pycfiles. In reality, the value isparsed as an integer flag: non-zero values disable bytecode generation,
while setting it to
0does not.This change updates the documentation to accurately reflect the actual
runtime behavior, keeping it consistent with how the variable is handled
in
Python/initconfig.c.Closes #143134
