Open pdf files format with python -

i try open 100 pdf files python 2.7 code:

import arcpy,fnmatch,os  rootpath = r"d:\desktop" pattern = '*.pdf' counter = 0 root, dirs, files in os.walk(rootpath):     filename in fnmatch.filter(files, pattern):         os.startfile(rootpath)         counter = counter + 1 print counter 

as result rootpath folder opened , python print number of pdf files:

>>>  39 >>>  

no pdf files opened. search in forum , didn't find question answers request.

i don't know trying do, os.startfile open adobe pdf reader (or other reader that's set default reader)... here how managed , seems working.

import os  rootpath = "d:\\desktop" counter = 0 file in os.listdir(rootpath):     if file.endswith('.pdf'):         os.startfile("%s/%s" %(rootpath, file))         counter = counter + 1 print counter 

or without editing main code

import arcpy,fnmatch,os  rootpath = r"d:\desktop" pattern = '*.pdf' counter = 0 root, dirs, files in os.walk(rootpath):     filename in fnmatch.filter(files, pattern):         os.startfile("%s/%s" %(rootpath,filename))         counter = counter + 1 print counter
