It's not a race. It's just redundant. If the file does not exist at the time you actually try to access it you get the same error with slightly better error message.

There is a log message that won't be output in that case: whether getting a full, "native" FileNotFound exception is better is beside the point, since the goal of the code was obviously to print a custom error message.

And it's trivial to achieve the desired effect sanely:

  try:
      with open(...) ...

  except FileNotFound:
      logger.error(...)
      raise

It'd even be fewer lines of code.

		Or even fewer by doing it in a global exception handler instead of every time you try to open a file, since all your doing is piping the error though logger.
