did you close the file correctly after processing it ?

>>> f = open("somefile.txt", "w")
>>> import os
>>> os.remove("somefile.txt")
Traceback (most recent call last):
  File "<stdin>", line 1, in ?
OSError: [Errno 13] Permission denied: 'somefile.txt'
>>> f.close()
>>> f = open("somefile.txt", "r")
>>> os.remove("somefile.txt")
Traceback (most recent call last):
  File "<stdin>", line 1, in ?
OSError: [Errno 13] Permission denied: 'somefile.txt'
>>> f.close()
>>> os.remove("somefile.txt")
>>>
