Python 捕获异常并继续

Question

I've a little script in python that work in loop. Every 30 seconds it get an url with requests to check if content of the page is changed.

But sometime I get script error (about 1 time a day):

ConnectionError: HTTPSConnectionPool(host='www.example.com', port=443): Max retries exceeded with url: /test/ (Caused by NewConnectionError(<urllib3.connection.VerifiedHTTPSConnection object at 0x.......>: [Errno -3] Temporary failure in name resolution))

What it the best way to intercept exception and, if occurs, wait another 30 seconds and continue the script instead stop it? The exception to caught is ConnectionError or NewConnectionError ?

Answer 1

Put a try/except around your code, like this:

try:

# your code here

except ConnectionError:
    pass
except NewConnectionError:
    pass
