Python How to ignore an exception and proceed

Question

I have a try   except block in my code and When an exception is throw  I really just want to continue with the code because in that case  everything is still able to run just fine  The problem is if you leave the except  block empty or with a  do nothing  it gives you a syntax error  I can t use continue because its not in a loop  Is there a keyword i can use that tells the code to just keep going

There s a new way to do this coming in Python 3 4   from contextlib import suppress  with suppress Exception       your code   Here s the commit that added it  http   hg python org cpython rev 406b47c64480  And here s the author  Raymond Hettinger  talking about this and all sorts of other Python hotness  relevant bit at 43 30   http   www youtube com watch v OSGv2VnC0go  If you wanted to emulate the bare except keyword and also ignore things like KeyboardInterrupt   though you usually don t   you could use with suppress BaseException    Edit  Looks like ignored was renamed to suppress before the 3 4 release

Generic answer  The standard  nop  in Python is the pass statement   try      do something   except Exception      pass   Using except Exception instead of a bare except avoid catching exceptions like SystemExit  KeyboardInterrupt etc   Python 2  Because of the last thrown exception being remembered in Python 2  some of the objects involved in the exception-throwing statement are being kept live indefinitely  actually  until the next exception   In case this is important for you and  typically  you don t need to remember the last thrown exception  you might want to do the following instead of pass   try      do something   except Exception      sys exc clear     This clears the last thrown exception   Python 3  In Python 3  the variable that holds the exception instance gets deleted on exiting the except block  Even if the variable held a value previously  after entering and exiting the except block it becomes undefined again
