I think you have to set PATH in environment variable for python command to work.If you're on windows follow this: 我认为您必须在环境变量中设置PATH才能使python命令正常工作。如果您在Windows上，请遵循以下步骤：

My Computer > Properties > Advanced System Settings > Environment Variables > Then under system variables create a new Variable name PATH.Under value type your python installation directory which includes py.exe etc(scripts folder).Then it'll work. 我的电脑>属性>高级系统设置>环境变量>然后在系统变量下创建一个新的变量名称PATH。在值下键入您的python安装目录，其中包括py.exe etc（scripts文件夹）。 OR open cmd prompt in python folder(shift+context menu click) and then enter command. 或在python文件夹中打开cmd提示符（单击Shift +上下文菜单），然后输入命令。
