PyCharm

PyCharm is an integrated development environment (IDE) used in computer programming, specifically for the Python language. It is developed by the Czech company JetBrains. It provides code analysis, a graphical debugger, an integrated unit tester, integration with version control systems (VCSes), and supports web development with Django as well as data science with Anaconda.

PyCharm is cross-platform, with Windows, macOS and Linux versions. The Community Edition is released under the Apache License, and there is also Professional Edition with extra features – released under a proprietary license.

Features

 * Coding assistance and analysis, with code completion, syntax and error highlighting, linter integration, and quick fixes
 * Project and code navigation: specialized project views, file structure views and quick jumping between files, classes, methods and usages
 * Python refactoring: includes rename, extract method, introduce variable, introduce constant, pull up, push down and others
 * Support for web frameworks: Django, web2py and Flask [professional edition only]
 * Integrated Python debugger
 * Integrated unit testing, with line-by-line code coverage
 * Google App Engine Python development [professional edition only]

It competes mainly with a number of other Python-oriented IDEs, including Eclipse's PyDev, and the more broadly focused Komodo IDE.
