Software Carpentry The Problem Many scientists and engineers spend much of their lives writing, debugging, and maintaining software, but only a handful have ever been taught how to do this effectively: after a couple of introductory courses, they are left to rediscover (or reinvent) the rest of programming on their own. The result? Most spend far too much time wrestling with software when they'd rather be doing research, but still have no idea how reliable or efficient that software is. The Solution This site presents an intensive course on basic software development practices for scientists and engineers. Download Python How to verify your downloaded files are genuine Sigstore verification Starting with the Python 3.11.0, Python 3.10.7, and Python 3.9.14 releases, CPython release artifacts are signed with Sigstore. OpenPGP verification Python versions before 3.14 are also signed using OpenPGP private keys of the respective release manager. See PEP 761 for why OpenPGP key verification was dropped in Python 3.14. Windows (Updated for Azure Trusted Signing, which applies for all releases chronologically from 3.14.0a1) The Windows installers and all binaries produced as part of each Python release are signed using an Authenticode signing certificate issued to the Python Software Foundation. macOS Installer Packages Installer packages for Python on macOS downloadable from python.org are signed with with an Apple Developer ID Installer certificate. Installer packages for previous releases were signed with certificates issued to Ned Deily (DJ3H93M7VJ). Other Useful Items Looking for third-party Python modules?

Welcome to Python.org Welcome - Learn Python - Free Interactive Python Tutorial PEP 20 -- The Zen of Python Abstract 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. The Zen of Python Beautiful is better than ugly. Explicit is better than implicit. Simple is better than complex. Easter Egg >>> import this Copyright This document has been placed in the public domain. The Python Tutorial Python is an easy to learn, powerful programming language. It has efficient high-level data structures and a simple but effective approach to object-oriented programming. Python’s elegant syntax and dynamic typing, together with its interpreted nature, make it an ideal language for scripting and rapid application development in many areas on most platforms. The Python interpreter and the extensive standard library are freely available in source or binary form for all major platforms from the Python Web site, and may be freely distributed. The same site also contains distributions of and pointers to many free third party Python modules, programs and tools, and additional documentation. The Python interpreter is easily extended with new functions and data types implemented in C or C++ (or other languages callable from C). This tutorial introduces the reader informally to the basic concepts and features of the Python language and system.
Functional Programming HOWTO — Python v2.7.8 documentation In this document, we’ll take a tour of Python’s features suitable for implementing programs in a functional style. After an introduction to the concepts of functional programming, we’ll look at language features such as iterators and generators and relevant library modules such as itertools and functools. Introduction This section explains the basic concept of functional programming; if you’re just interested in learning about Python language features, skip to the next section. Programming languages support decomposing problems in several different ways: Most programming languages are procedural: programs are lists of instructions that tell the computer what to do with the program’s input. The designers of some computer languages choose to emphasize one particular approach to programming. In a functional program, input flows through a set of functions. Functional programming can be considered the opposite of object-oriented programming. Formal provability Modularity Composability Iterators
Perl Though Perl is not officially an acronym,[5] there are various backronyms in use, such as: Practical Extraction and Reporting Language.[6] Perl was originally developed by Larry Wall in 1987 as a general-purpose Unix scripting language to make report processing easier.[7] Since then, it has undergone many changes and revisions. The latest major stable revision of Perl 5 is 5.18, released in May 2013. Perl 6, which began as a redesign of Perl 5 in 2000, eventually evolved into a separate language. History[edit] Early versions[edit] Wall began work on Perl in 1987, while working as a programmer at Unisys,[9] and released version 1.0 to the comp.sources.misc newsgroup on December 18, 1987.[14] The language expanded rapidly over the next few years. Perl 2, released in 1988, featured a better regular expression engine. Originally the only documentation for Perl was a single (increasingly lengthy) man page. Early Perl 5[edit] Perl 5.001 was released on March 13, 1995. 2000–present[edit]
labs :: Python beginner's mistakes Every Python programmer had to learn the language at one time, and started out as a beginner. Beginners make mistakes. This article highlights a few common mistakes, including some I made myself. Beginner's mistakes are not Python's fault, nor the beginner's. To put it another way, the mistakes in this article are often cases of "the wrong tool for the job", rather than coding errors or sneaky language traps. Mistake 1: trying to do low-level operations Python is sometimes described as a VHLL, a Very High-Level Language. This doesn't mean that it isn't possible to do these things with Python; but it's probably just not the right language for these jobs. Mistake 2: writing "language X" code in Python This is a mistake that is almost unavoidable. Some notorious symptoms of "language X" code, and the languages that may cause them: The point here is not to slam the language that you're used to (although that is always fun ;-). This one requires some clarification. Some advice
Python Software Foundation From Wikipedia, the free encyclopedia American nonprofit organization In 2005, the Python Software Foundation received the Computerworld Horizon Award for "cutting-edge" technology.[4][5] Overview[edit] The PSF focuses on empowering and supporting people within the Python community with grant programs that support sprints, conferences, meetups, user groups, and Python development. Membership[edit] There are five tiers of membership within the PSF. Basic members – Basic members are individuals or entities who are part of the Python language community and who have decided to declare their support for Python and agree to the community Code of Conduct.Supporting members – Supporting members make an annual donation to the PSF to sustain the foundation and support the Python community. Code of Conduct[edit] Since late 2012, the Python Software Foundation started recommending that all Python conferences create and apply a code of conduct.

C Sharp (programming language) C♯ is intended to be a simple, modern, general-purpose, object-oriented programming language.[6] Its development team is led by Anders Hejlsberg. The most recent version is C♯ 5.0, which was released on August 15, 2012. The ECMA standard lists these design goals for C#:[6] Due to technical limitations of display (standard fonts, browsers, etc.) and the fact that the sharp symbol (U+266F ♯ music sharp sign (HTML: ♯)) is not present on the standard keyboard, the number sign (U+0023 # number sign (HTML: #)) was chosen to represent the sharp symbol in the written name of the programming language.[8] This convention is reflected in the ECMA-334 C# Language Specification.[6] However, when it is practical to do so (for example, in advertising or in box art[9]), Microsoft uses the intended musical symbol. C# used to have a mascot called Andy (named after Anders Hejlsberg). In the course of its development, the C# language has gone through several versions: C# has the following syntax:
