Maybe it's really a problem of platform dependency. Take a look at this
brief example, (not using urllib, but just want to show the platform
dependency of python):

Here is the snapshot from dos:

D:\>python
ActivePython 2.4.1 Build 247 (ActiveState Corp.) based on
Python 2.4.1 (#65, Jun 20 2005, 17:01:55) [MSC v.1310 32 bit (Intel)]

>>> f = open("t", "r")
>>> f.tell()
0L
>>> f.readline()
'http://cn.realestate.yahoo.com\n'
>>> f.tell()
28L
