ID: python-best-practices/finally-no-break-continue-return
Language: Python
Severity: Warning
Category: Best Practices
When using return
, break
or continue
in a finally
block, it will stop the spread of any exceptions that were thrown in the try
, else
, or except
blocks and will disregard any return statements.
try:
client_obj.get_url(url)
except (URLError, ValueError):
client_obj.remove_url(url)
except SocketTimeout:
client_obj.handle_url_timeout(url)
finally:
break # avoid break in the finally block
try:
client_obj.get_url(url)
except (URLError, ValueError):
client_obj.remove_url(url)
except SocketTimeout:
client_obj.handle_url_timeout(url)
finally:
return 0 # avoid return in the finally block
try:
client_obj.get_url(url)
except (URLError, ValueError):
client_obj.remove_url(url)
except SocketTimeout:
client_obj.handle_url_timeout(url)
finally:
continue # avoid continue in the finally block
try:
client_obj.get_url(url)
except (URLError, ValueError):
client_obj.remove_url(url)
except SocketTimeout:
client_obj.handle_url_timeout(url)
finally:
print("cleanup the mess")
