This document gives coding conventions for the Python code comprising the standard library in the main Python distribution. Please see the companion informational PEP describing style guidelines for the C code in the C implementation of Python.
Long time Pythoneer Tim Peters succinctly channels the BDFL’s guiding principles for Python’s design into 20 aphorisms, only 19 of which have been written down.
(This is a modified version of the keynote talk given by Rob Pike at the SPLASH 2012 conference in Tucson, Arizona, on October 25, 2012.)
People occasionally ask why LLVM-compiled code sometimes generates SIGTRAP signals when the optimizer is turned on. After digging in, they find that Clang generated a "ud2" instruction (assuming X86 code) - the same as is generated by __builtin_trap().
Clojure is a dynamic language. Among other things this means that type annotations are not required for code to run. While Clojure has some support for type hints, they are not an enforcement mechanism, nor comprehensive, and are limited to communicating information to the compiler to aid in efficient code generation…
This PEP outlines the behavior of Python scripts when the python command is invoked. Depending on a distribution or system configuration, python may or may not be installed. If python is installed its target interpreter may refer to python2 or python3. ...
This is a proposal for creating a way to assign to variables within an expression using the notation NAME := expr.
Starting Forth has always been the fun way to learn Forth programming. This free, online edition uses updated code that runs on modern Forth systems.
A technical talk about the structure and details of the new, low-latency Go garbage collector.
The spec library ( API docs ) specifies the structure of data, validates or conforms it, and can generate data based on the spec.
In Part 1 of our series, we discussed what undefined behavior is, and how it allows C and C++ compilers to produce higher performance applications than "safe" languages. This post talks about how "
This post explains why Rust made sense for Discord to reimplement: how it was done, and the resulting performance improvements.
A Programmer's Best Friend
The programming language Pascal has become the dominant language of instruction in computer science education. It has also strongly influenced languages developed subsequently, in particular Ada.
Focus on debugging your application rather than debugging your programming language knowledge.
If Zig code doesn’t look like it’s jumping away to call a function, then it isn’t. This means you can be sure that the following code calls only foo() and then bar() , and this is guaranteed without needing to know the types of anything:
Idioms and patterns for handling errors in Go.
In short, because we are greedy....
Watch Rob Pike's talk, _Concurrency is not parallelism._
This PEP introduces a syntax for adding arbitrary metadata annotations to Python functions 1.
C is arguably the world’s most successful programming language. Its success has, of course, endlessly tempted people to improve upon it. Thus, C is probably the patriarch of the longest list of languages. Notable among these are C++, the D programming language, and most recently, Go. There are endless discussion…
Nim is advancing towards more efficient memory management models. Let's talk about ARC/ORC and see how they will change the way memory works in Nim.
This PEP proposes the merger of the Unladen Swallow project 3 into CPython’s source tree. Unladen Swallow is an open-source branch of CPython focused on performance. Unladen Swallow is source-compatible with valid Python 2.6.4 applications and C extensi...
In Part 1 of the series, we took a look at undefined behavior in C and showed some cases where it allows C to be more performant than "safe" languages.
An introduction to the Go's defer, panic, and recover control flow mechanisms.
