Maybe because…

…this line will raise an exception.  `file.write()` takes just one
argument, not three as in this call.  If you don't get an exception maybe
you have other places with a bare ``except`` like in the snippet above. 
Don't do that.  Catch the specific exception you want to handle with an
``except`` and not simply *all*.
