python（2.7.10） 安装后启动错误:IDLE's subprocess didn't make connection

问题：
启动Python提示错误：
IDLE‘s subprocess didn‘t make connection.Either IDLE can’t start a subprocess or personal firewall software is blocking the connection 。

原因：

That usually means that your firewall is blocking IDLE, so  enable it in your firewall. If that doesnt work, do this to fix

it (with some disavantages):

解决办法：

1.打开 C:/Python24/Lib/idlelib/PyShell.py（Python安装目录）

将
use_subprocess = True

改为

use_subprocess = False

2. 删除PyShell.pyc
