Source: Python.org The Terms ‘Interactive’ and ‘Shell’ The term “interactive” traces back to the Latin expression “inter agere”. The verb “agere” means amongst other things “to do something” and “to act”, while “inter” denotes the spatial and temporal position to things and events, i.e. “between” or “among” objects, persons, and events. So “inter agere” means “to act between” or “to act among” these. With this in mind, we can say that the interactive shell is between the user and the operating system (e.g. Linux, Unix, Windows or others). Instead of an operating system an interpreter can be used for a programming language like Python as well. The Python interpreter can…

Virtualenv
Source: VirtualEnv virtualenv is a tool to create isolated Python environments. Since Python 3.3, a subset of it has been integrated into the standard library under the venv module. The venv module does not offer all features of this library, to name just a few more prominent: is slower (by not having the app-data seed method), is not as extendable, cannot create virtual environments for arbitrarily installed python versions (and automatically discover these), is not upgrade-able via pip, does not have as rich programmatic API (describe virtual environments without creating them). The basic problem being addressed is one of dependencies and versions, and indirectly permissions. Imagine you have an application that needs version 1 of LibFoo, but another application requires version 2.…

What is Python? Powerful, intuitive programming
Why the Python programming language shines for data science, machine learning, systems automation, web and API development, and more Source: Infoworld.comDating from 1991, the Python programming language was considered a gap-filler, a way to write scripts that “automate the boring stuff” (as one popular book on learning Python put it) or to rapidly prototype applications that will be implemented in other languages. However, over the past few years, Python has emerged as a first-class citizen in modern software development, infrastructure management, and data analysis. It is no longer a back-room utility language, but a major force in web application creation and systems management, and a key driver of the explosion in big…

What is Python?
Python is an interpreted, object-oriented, high-level programming language with dynamic semantics, Created by Guido van Rossum and first released in 1991, Python’s design philosophy emphasizes code readability with its notable use of significant whitespace. Its language constructs and object-oriented approach aim to help programmers write clear, logical code for small and large-scale projects. Its high-level built in data structures, combined with dynamic typing and dynamic binding, make it very attractive for Rapid Application Development, as well as for use as a scripting or glue language to connect existing components together. Python’s simple, easy to learn syntax emphasizes readability and therefore reduces the cost of program maintenance. Python supports modules and packages, which encourages program modularity and code reuse. The Python interpreter…
