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
