OsError Python on Ubuntu

I have created a script with Python and when executing it, it responds with this message:

Traceback (most recent call last):
  File "./pruebaHIDS.py", line 6, in <module>
    for filename in listdir("/Escritorio/Scripts"):
OSError: [Errno 2] No such file or directory: '/Escritorio/Scripts'

The problem comes because the directory in particular Desktop / Scripts is not empty.

Does anyone think of a solution or has it happened before?

Edit:

Changing the path to "/ home / ldh / Desktop / Scripts /" as advised in the comments I get a new error:

Traceback (most recent call last): 
  File "pruebaHIDS.py", line 11, in <module>
    print "excepción: " % e
TypeError: not all arguments converted during string formatting

I enclose the code that I am running:

#!/usr/bin/python
# -*- coding: utf-8 -*-
import hashlib
from os import listdir
from os.path import isdir, islink
for filename in listdir("/home/ldh/Escritorio/Scripts/"):
 if not isdir(filename) and not islink(filename):
  try:
   f = open(filename)
  except IOError, e:
   print "excepción: " % e
 else:
  data = f.read()
  f.close()
  print "** %s **" % filename
  for algorithm in hashlib.algorithms:
   h = getattr(hashlib, algorithm)(data)
   print "%s: %s" % (algorithm, h.hexdigest())
   print ""
