TimeoutError

built-in exceptions

A system function timed out (a subclass of OSError).

Syntax

raise TimeoutError

It only shows up where a timeout was actually set — socket.settimeout(), a timeout= argument to a network client; your own slow loop will never raise it on its own. Since Python 3.10 socket.timeout, and since 3.11 asyncio.TimeoutError as well, are just other names for this same built-in class, so a single except TimeoutError covers all three. Note that subprocess has its own TimeoutExpired, which this except will not catch.

Examples

try:
    raise TimeoutError
except TimeoutError as e:
    print(type(e).__name__)   # → TimeoutError
