问题描述：

我已经安装了 python 3.1，并且我也将它添加到了系统路径中.现在我可以打开cmd"并输入python来启动python，但是每当我尝试使用(shift+右键单击->在此处打开命令提示符)在特定目录中打开cmd并输入python时，它会显示找不到命令！

I have python 3.1 installed, and I have added it to the system path too. Now I can open "cmd" and type python to start python, but whenever I try to open cmd in a specific directory by using (shift + right click -> open command prompt here), and type python, it says "command not found"!
