Change the drive, directories and file name to match your case and try this:

import os

def fileChk(file_name):
    try:
        f = open(file_name, "r")
        f.close()
        return True
    except IOError, e:
        # unable to open file
        return False

dir_name = (os.path.join('C:\\', 'SDS2_7.0', 'macro'))
file_name = ("your_file.dat")
if fileChk(os.path.join(dir_name, file_name)):
    print "Success!"
else:
    print "File does not exist"

check out os.path.exists( ) . It should do what you want.

Good point ghostdog74. Thanks!

if os.path.exists(os.path.join(dir_name, file_name)):
    print "Success!"
else:
    print "File does not exist"
