PEP 394 -- The "python" Command on Unix-Like Systems
Abstract This PEP provides a convention to ensure that Python scripts can continue to be portable across *nix systems, regardless of the default version of the Python interpreter (i.e. the version invoked by the python command). python2 will refer to some version of Python 2.x. python3 will refer to some version of Python 3.x. for the time being, all distributions should ensure that python refers
PEP 3156 -- Asynchronous IO Support Rebooted: the "asyncio" Module
Abstract This is a proposal for asynchronous I/O in Python 3, starting at Python 3.3. Consider this the concrete proposal that is missing from PEP 3153. The proposal includes a pluggable event loop, transport and protocol abstractions similar to those in Twisted, and a higher-level scheduler based on yield from (PEP 380). The proposed package name is asyncio. Status A reference implementation exis
PEP 465 -- A dedicated infix operator for matrix multiplication
No implementations of these methods are added to the builtin or standard library types. However, a number of projects have reached consensus on the recommended semantics for these operations; see Intended usage details below for details. For details on how this operator will be implemented in CPython, see Implementation details. Executive summary In numerical code, there are two important operatio
PEP 3107 -- Function Annotations
Abstract This PEP introduces a syntax for adding arbitrary metadata annotations to Python functions [1]. Rationale Because Python's 2.x series lacks a standard way of annotating a function's parameters and return values, a variety of tools and libraries have appeared to fill this gap. Some utilise the decorators introduced in "PEP 318", while others parse a function's docstring, looking for annota
PEP 0 -- Index of Python Enhancement Proposals (PEPs)
David Goodger <goodger at python.org>, Barry Warsaw <barry at python.org> Introduction This PEP contains the index of all Python Enhancement Proposals, known as PEPs. PEP numbers are assigned by the PEP editors, and once assigned are never changed[1]. The Mercurial history[2] of the PEP texts represent their historical record.
