| Hi,
|
| I wrote some python code that retrieves urls from a txt file. In this
| code I use .rstrip() for removing the '\n' at the end of every url.
| While this code works on my mac (leopard) with python 2.5.1, this same
| code fails to work on an ubuntu server with python 2.4.3
|
| I was wondering if there is a problem with .rstrip() in that python
| version?
|
| error :
| Traceback (most recent call last):
|  File "delgraph.py", line 62, in ?
|    url_metadata = d.get_url(site.rstrip())
| -- 

What is the actual error message [SyntaxError, NameError? etc] that you 
clipped?
