IDLE is an integrated development environment for Python, which is a high-level programming language. It’s part of the standard Python distribution and supports both Python 2 and Python 3. The name IDLE is not an acronym, but a tribute to Eric Idle, a member of the British comedy group Monty Python, which the Python language itself is named after.

IDLE includes a multi-window text editor for Python files, with features such as syntax highlighting, smart indentation, and an integrated debugger. It also includes a Python shell window, which enables interactive testing and debugging of snippets of Python code.

IDLE is written in pure Python, using the tkinter GUI toolkit. It’s a cross-platform application, meaning it can run on multiple operating systems, including Windows, macOS, and Linux. It’s also extensible and can be customised using Python code.

The IDLE environment has a simple and minimalistic design, making it suitable for beginners. However, some Python developers prefer more sophisticated environments, such as PyCharm or Jupyter Notebook, which offer more advanced features. Despite this, IDLE remains a popular choice for Python programming, particularly in educational settings.
