该问题主要是参考博文：http://blog.csdn.net/pengchua/article/details/3097319
自己也记录下。
问题：
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
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):
Open C:/Python24/Lib/idlelib/PyShell.py
at the 1272 line（我的是在1332行，就在main()函数下方的位置处）
change
use_subprocess = True
to
use_subprocess = False
同时删除PyShell.pyc
