Installing

Certain packages like libsqlite3-dev and libreadline-dev need to be installed before hand.

to check

  • pythonz is a program to automate the building and installation of Python in the users $HOME. This is a fork of the original project, pythonbrew.

Compiling

./configure --prefix=/opt/python2.7 --with-threads --enable-shared
make; make install

Setup aliases and path.

If error while loading shared libraries: libpython2.7.so.1.0 

echo "/opt/python2.7/lib" > /etc/ld.so.conf.d/libpython2.7.conf
ldconfig

 curl http://python-distribute.org/distribute_setup.py | python

Packages




PyPI

The Python Package Index is a repository of software for the Python programming language.

pip

  • pip is a tool for installing and managing Python packages, such as those found in the Python Package Index. It’s a replacement for easy_install.


Tools

Tools




  • https://github.com/klen/pylama - Code audit tool for Python and JavaScript. Pylama wraps these tools: pycodestyle (formerly pep8), pydocstyle, PyFlakes, Mccabe, Pylint, Radon, gjslint




  • VizTracer - a low-overhead logging/debugging/profiling tool that can trace and visualize your python code to help you intuitively understand your code and figure out the time consuming part of your code. VizTracer can display every function executed and the corresponding entry/exit time from the beginning of the program to the end, which is helpful for programmers to catch sporadic performance issues.

IDE

See also Development#IDE

  • IDLE - Python’s Integrated Development and Learning Environment.


  • PyCharm - provides smart code completion, code inspections, on-the-fly error highlighting and quick-fixes, along with automated code refactorings and rich navigation capabilities.


  • The Eric Python IDE - a full featured Python editor and IDE, written in Python. It is based on the cross platform Qt UI toolkit, integrating the highly flexible Scintilla editor control. It is designed to be usable as everdays' quick and dirty editor as well as being usable as a professional project management tool integrating many advanced features Python offers the professional coder. eric includes a plug-in system, which allows easy extension of the IDE functionality with plug-ins downloadable from the net.


  • Spyder IDE - The Scientific PYthon Development EnviRonment is a powerful interactive development environment written in Python for Python, with advanced editing, interactive testing, debugging, introspection features and a computing environment for the desktop!


  • NINJA IDE - from the recursive acronym: "Ninja-IDE Is Not Just Another IDE", is a cross-platform integrated development environment (IDE). NINJA-IDE runs on Linux/X11, Mac OS X and Windows desktop operating systems, and allows developers to create applications for several purposes using all the tools and utilities of NINJA-IDE, making the task of writing software easier and more enjoyable.


  • PyDev - a Python IDE for Eclipse, which may be used in Python, Jython and IronPython development.


  • PyScripter - an open-source Python Integrated Development Environment (IDE) created with the ambition to become competitive in functionality with commercial IDEs available for other languages. It is a feature-rich but also lightweight.


  • Thonny - Python IDE for beginners




  • Leo's Home Page - a PIM, IDE and outliner that accelerates the work flow of programmers, authors and web designers. Outline nodes may appear in more than one place, allowing multiple organizations of data within a single outline. [3]

Project environment


virtualenv

  • virtualenv is a tool to create isolated Python environments. 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. How can you use both these applications? If you install everything into /usr/lib/python2.7/site-packages (or whatever your platform’s standard location is), it’s easy to end up in a situation where you unintentionally upgrade an application that shouldn’t be upgraded.


"Now, you’re ready to create your virtualenv. BUT FIRST…you have a decision to make. Do you want this virtualenv to use packages from your system site-packages on install them in the virtualenv’s site-packages? By default, virtualenv will symlink to your system’s site-packages if you install a package in the virtualenv that is already installed on your system. If you want a totally (well, as much as is possible) isolated virtualenv, you’ll want to do the latter. To do this, you pass in the -–no-site-packages switch when creating your virtualenv." 



pip -E [envname] [package]
  install package in specific virtual environment

Or install pip seperatly in an env and use from there.


pyenv

pipx

Implementations




  • https://github.com/pannous/angle - the Python implementation of English as a programming language. Since Angle compiles to Python bytecode, it is can be used as a drop-in-replacement for classic Python and is fully debuggable, even in PyCharm. It is currently in development to be run directly in WASM via wasp.The main purpose of this language is to facilitate programming computers via voice. Angle is the first speakable programing language and thus makes programing accessible to many more people.


Interfaces




Web

python -m SimpleHTTPServer
  start http server on port 8000 [6]
python -m SimpleHTTPServer 3131
  start http server on poty 3131


Libraries and modules

  • Aaargh - an astonishingly awesome application argument helper
  • sh - a full-fledged subprocess interface for Python that allows you to call any program as if it were a function


  • attrs - the Python package that will bring back the joy of writing classes by relieving you from the drudgery of implementing object protocols (aka dunder methods).Its main goal is to help you to write concise and correct software without slowing down your code.



Maths


Serialisation


Interactive

  • https://github.com/python-cmd2/cmd2 - a tool for building interactive command line applications in Python. Its goal is to make it quick and easy for developers to build feature-rich and user-friendly interactive command line applications. It provides a simple API which is an extension of Python's built-in cmd module. cmd2 provides a wealth of features on top of cmd to make your life easier and eliminates much of the boilerplate code which would be necessary when using cmd.


  • Click - a Python package for creating beautiful command line interfaces in a composable way with as little code as necessary. It’s the “Command Line Interface Creation Kit”. It’s highly configurable but comes with sensible defaults out of the box.It aims to make the process of writing command line tools quick and fun while also preventing any frustration caused by the inability to implement an intended CLI API.

TUI


Network

  • Eve - an open source Python REST API framework designed for human beings. It allows to effortlessly build and deploy highly customizable, fully featured RESTful Web Services. Eve is powered by Flask and Cerberus and it offers native support for MongoDB data stores. Support for SQL, Elasticsearch and Neo4js backends is provided by community extensions.


Web

  • Syte - a really simple but powerful packaged personal site that has social integrations like Twitter, GitHub, Dribbble, Instagram, Foursquare, Tumblr, Last.fm, SoundCloud and Bitbucket. You can see it in action on my personal site.
  • Pattern - a web mining module for the Python programming language. It bundles tools for: Data Mining: Google + Twitter + Wikipedia API, web spider, HTML DOM parser, Natural Language Processing: tagger/chunker, n-gram search, sentiment analysis, WordNet, Machine Learning: vector space model, k-means clustering, Naive Bayes + k-NN + SVM classifiers, Network Analysis: graph centrality and visualization.
  • Tornado - an open source version of the scalable, non-blocking web server and tools that power FriendFeed.

Data

  • dataset - Because managing databases in Python should be as simple as reading and writing JSON files.

Visual

See also Visulisation

  • Python Imaging Library (PIL) adds image processing capabilities to your Python interpreter. This library supports many file formats, and provides powerful image processing and graphics capabilities.
