What is your question?
If it's about the type of exception raised when os.path.exists fails, well, sure it's hard to find:

  print os.path.exists("foo".bar)
  ==> False

The output beeing a logical value, there is no failure.
A general method to get a type of exception matching a particuliar kind of error is to provoke an error of this given kind, eg:

  f = file("foo.bar")
  ==>
Traceback (most recent call last):
  File "__essai__.py", line 10, in <module>
    f = file("foo.bar")
IOError: [Errno 2] No such file or directory: 'foo.bar'

In this case, the type is IOError.
