Problem with os.path

[Daya Kiran Sunkara]

Hi All,

I have a program which fetches the list of files inside a directory.
For fetching this list I am making use of the glob.glob method which
takes path as a parameter.
For building the path I am making use of os.path.join. My code looks
somewhat like this:
-----------------------------------------------------------------------
import glob
import os
path = 'E:\mktrisk\service\marketdata\da'
for filename in glob.glob(os.path.join(path,'*.java')):
datafile = open(filename,'r').readlines()
----------------------------------------------------------------------

this program works fine when the string 'path' is not too long. When I
pass a longer string as path, the program doesn't work. Now I am not
sure whether its a limitation with the string class or with os.path. I
am passing a valid path to the program and I am running this on Python
2.4.2 on Windows XP.

Any help will be greatly appreciated.

regards,
Daya

sorry? if i'm wrong? but i'm think you have to use double slash, to
prevent escape-interpreting as '\n' for example

...
path = 'E:\mktrisk\service\marketdata\da'

You should use:
path = r'E:\mktrisk\service\marketdata\da'
if you want to use backslashes regularly (for regexps and paths).
You do know you could also use:
path = 'E:/mktrisk/service/marketdata/da'
even on windows.
