I'm trying to rename some PDF files using pyPdf and my code it seems to work fine until it reaches the rename sentence. The While/if block of code looks for the page number where string "This string" is located and when found stops. Having the page number the "new name" is created.

My issue is that even when the with block it's supposed to close automatically the file, when it's reached the rename sentence I get the error below

Traceback (most recent call last):
File "<stdin>", line 14, in <module>
WindowsError: [Error 32] The process cannot access the file because it is being used by another process

and I don't know how to close the file before rename it, since if I use "file.close()" I get this error

Traceback (most recent call last):
File "<stdin>", line 14, in <module>
AttributeError: 'str' object has no attribute 'close'

My current code is below, thanks for any help on this.

import os
import glob
import sys
from os.path import basename
import pyPdfpath = "C:\\My\\Path\\"
os.chdir(path)  
for file in glob.glob("*.pdf"):print filei = 0with open(file, "rb") as f:pdf = pyPdf.PdfFileReader(f)while True:txt = pdf.pages[i].extractText()if "This string" in txt:new_name = basename(file) + "_Page_" + str(i)breaki = i + 1   print new_name#file.close()os.rename(file, new_name) # The error occurs here.

* Update *

Without With block I get the same error

for file in glob.glob("*pdf"):print filei = 0   f = open(file, "rb") pdf = pyPdf.PdfFileReader(f)while True:txt = pdf.pages[i].extractText()if "This string" in txt:new_name = basename(file) + "_Page_" + str(i)break           i = i + 1   f.close()   os.rename(file, new_name)

Thanks your advice .But,I remove the variable in my program,and successed. :) In my view ,the file was surely opened in my program ,but I dont know how to c lose it,So I clean All. :(
