How to get function name which raised IOError/OSError?

[Inyeol Lee]

Is there any way to get function name which raised IO/OSError?
I want to write an error message formatter like;

def print_oserror():
  e = sys.exc_info()
  func = get_func(e)   # I don't know how to implement this.
  print "cannot %s %s: %s." % (func, e[1].filename, e[1].strerror)

try:
  os.mkdir("foo")
  os.chdir("bar")
  os.rmdir("baz")
except OSError:
  print_oserror()  # print message like 'cannot chdir bar: blabla...'

Thanks,
