Looks to me like your "urllib2.urlopen(url).read()" call
fails. UnboundLocalError means that 'rawtweets' wasn't assigned, and it is
only assigned if this call returns successfully.
Here is another example for this:
"""
>>> def raise_error():
... raise ValueError("i'm an error")
...
>>> def look_ma_referenced_before_assignment():
... try:
... x = raise_error()
... except ValueError, e:
... print e
... print x
...
>>> look_ma_referenced_before_assignment()
i'm an error
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "<stdin>", line 6, in look_ma_referenced_before_assignment
UnboundLocalError: local variable 'x' referenced before assignment
"""
So I would check if "urllib2.urlopen(url).read()" actually works. For
example:
- check if an error message is printed
- catch all errors, not just urllib2 errors.
cheers,
