Hello,
I am trying to learn how to use python with Facebook's Open Graph API. I am
getting my feet wet with the following code authored by Matthew A. Russell. I
copied it line for line for learning purposes, but I am getting the following
error:
Traceback (most recent call last):
File
"C:\Python27\Lib\site-packages\pythonwin\pywin\framework\scriptutils.py", line
325, in RunScript
exec codeObject in __main__.__dict__
File "C:\Python27\Scripts\facebook__query.py", line 20, in <module>
Q = sys.argv[1]
IndexError: list index out of range
Here is the code that this error is resulting from:
#Querying the Open Graph for "programming" groups
import sys
import json
import facebook
import urllib2
from facebook__login import login
try:
ACCESS_TOKEN =
open('C:\Users\Jon\Documents\FacebookApps\facebook.access_token').read()
except IOError, e:
try:
#Page 283 in Mining... for notes
ACCESS_TOKEN = sys.argv[1]
Q = sys.argv[2]
except:
print >> sys.stderr, \
"Could not either find access token in
'C:\Users\Jon\Documents\FacebookApps\facebook.access_token' or parse args."
ACCESS_TOKEN = login()
Q = sys.argv[1]
LIMIT = 100
gapi = facebook.GraphAPI(ACCESS_TOKEN)
...
...
Clearly this has something to do with sys.argv[1], and I think I'm getting an
IOError somewhere along the line.
I have tried quite hard to figure this out on my own using the Python tutorial,
Google, and the book in which the code was found to no avail. Please help!
Thanks,
Jon
