To set up the Python developing environment, there are several setps to follow:
1. Download and install the Python installer.
2. After the installation, if the path of Python is set, skip this step. Set "PYTHON_HOME" and add "PYTHON_HOME" into Path. The "PYTHON_HOME" should direct to where your python installation directory is, e.g:"C:\Python27" by default. To check whether the path is set successfully, open "cmd" console, run "python". If the python interface comes out, it means success.
3. Choose an IDE to develop. After comparison, I choose Eclipse+PyDev to develp. The eclipse I choose is "eclipse-jee-helios-SR1-win32", which is v3.6.1.
4. Install PyDev plugin for Eclipse with the URL "http://pydev.org/updates" in "Help=>Install New Software". Or install with the zip file at local.
After the steps, the Python development environment has been set successfully.
