PEP: 0 Title: Index of Python Enhancement Proposals (PEPs) Version: $Revision$ Last-Modified: $Date$ Author: David Goodger , Barry Warsaw Status: Active Type: Process Created: 13-Jul-2000 Post-History: Introduction The PEP contains the index of all Python Enhancement Proposals, known as PEPs. PEP numbers are assigned by the PEP Editor, and once assigned are never changed. The SVN history[1] of the PEP texts represent their historical record.
