Best Python IDEs and Code Editors 2021

A source-code editor is a text editor program designed specifically for editing source code of computer programs. It may be a standalone application or it may be built into an integrated development environment (IDE) or web browser. Source-code editors are a fundamental programming tool, as the fundamental job of programmers is to write and edit source code.

An integrated development environment (IDE) is a software application that provides comprehensive facilities to computer programmers for software development. An IDE normally consists of at least a source code editor, build automation tools and a debugger.

Python IDLE

It is Python’s Integrated Development and Learning Environment.

IDLE has the following features:

  • coded in 100% pure Python, using the tkinter GUI toolkit
  • cross-platform: works mostly the same on Windows, Unix, and macOS
  • Python shell window (interactive interpreter) with colorizing of code input, output, and error messages
  • multi-window text editor with multiple undo, Python colorizing, smart indent, call tips, auto completion, and other features
  • search within any window, replace within editor windows, and search through multiple files (grep)
  • debugger with persistent breakpoints, stepping, and viewing of global and local namespaces
  • configuration, browsers, and other dialogs
