# Getting wrong answer on submission but test cases are running fine (ZCO12001)

except:
pass

As you are using try except, you won’t know whether it is wrong answer or run time error.
Try block catches the error and starts running from except block. So, till then whatever is printed(even if nothing is printed), that wont match the expected output.

If I ruled the world, everyone who recommended using `try``except` blocks to “fix” runtime errors in Python would be banned from using their computer for a month

Edit:

Please Like @vasu_vg’s post above rather than mine, as he actually explains why it’s bad

Edit2:

Oh, great - now I’ve bumped this ancient thread to the top XD Soz!
