There are many Python editors. For details, see http://wiki.python.org/moin/pythoneditors. The official idle, pythonwin, and eclipse (pydev) are recommended.
Idle can be obtained after the official Python software package is installed, and pythonwin can be obtained by installing activepython. Pydev is a plug-in used to expand eclipse. After installation, you can use eclipse to develop python.

1. Install eclipse
Eclipse can be found and downloaded on eclipse.org, the official website. Generally, we can select an eclipse version suitable for ourselves, such as Eclipse classic. After the download is complete, decompress the package to the directory you want to install.
