几个月前，我在tkinter中编写了一个魔镜代码。当我做到这一点时，它就可以继续进行而没有任何问题。由于驱动器问题，我不确定这是我的最终产品（为此我也已经将Calendar切出了），但是无论何时，当我切断Internet时，它通常都没有响应。如何使它平稳运行？我意识到这是一个很大的部分，感谢能获得的任何帮助。

您可以使用以下命令继续检查Internet，然后，如果有Internet，则可以执行代码。如果没有，您可以让用户知道没有连接。
import socket
REMOTE_SERVER = "www.google.com"
def is_connected(hostname):
try:
host = socket.gethostbyname(hostname)
s = socket.create_connection((host, 80), 2)
return True
except:
pass
return False
