python 错误

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
change
use_subprocess = True

to

use_subprocess = False

同时删除PyShell.pyc
