python requests generic exception handling [duplicate]

Question

Within my code, all requests have a timeout period. And for each request, I have to handle the Timeout exception. Is there any way to attach a global Timeout exception handler with the requests?

try:
  request = requests.post(url=url1, data=data, headers=headers, timeout=Config.REQUEST_TIMEOUT)
except Timeout:
  raise ServiceUnavailable()

try:
  request = requests.post(url=url2, data=data, headers=headers, timeout=Config.REQUEST_TIMEOUT)
except Timeout:
  raise ServiceUnavailable()

Like above I every time I have to handle timeout and raise service unavailable. I want something generic, whenever timeout occurs it will raise service unavailable.

wrap you requests in a try/except block? without seeing your code its hard to give you any sort of advice — Nullman

@Nullman I have updated the question, hope you will understand — Minuddin Ahmed Rana

you could subclass requests and decorate the post method to handle the exception internally, that way you wont have to keep writing the same exception handler over and over — Nullman

Does this answer your question? how to not have the flask server break when an error occurs? — Gaurav Agarwal

Solved the problem using a different way. I am using flask, so I have added an error handler for Timeout exception

@app.errorhandler(requests.exceptions.Timeout)
def third_party_communication_handler(e):
    raise ServiceUnavailable()
