Yes, i can run scripts from /cgi-bin/. Actually I follow you example and it works really well. I didn't know at all about this CGI server. I am doing the hole thing over python now, it's nice.

I'm currently working in something similar, but I am having problems with getting data from the CCD (basically i don't know how to do it :), can you give me a tip for doing this? Or explain how you did it please? I not a newbie at python but not as experienced as evidently you are.

Tweepy: Invalid arguments at function call (tweepy.Stream())
Hi i'm trying to fetch realtime data from twitter using tweepy.Stream(). So I have tried the following... After successfully authenticate using oauth: auth = tweepy.OAuthHandler(...) (it works fine, i have my access_token.key and secret) i did: streaming_api = tweepy.streaming.Stream(auth, CustomStreamListener(), timeout='90') and: streaming_api = tweepy.streaming.Stream(auth, CustomStreamListener(), timeout='90') none of this works, it keeps giving me the same error: Traceback (most recent call last): File "", line 1, in streaming_api = tweepy.streaming.Stream(auth, CustomStreamListener(), timeout='60') TypeError: *init*() takes at least 4 arguments (4 given) then i have searched for the parameters of the function: tweedy.streaming.Stream(login,password,Listener(),...etc) but i thought this login and pass was the authentication method using in the basic authentication not in the oauth case. Now i'm really confused, a little help please? pd: As you can see, i'm trying to get realtime data from twitter (and make some further NLP with it), i have chose tweepy because the dev.twitter.compage recommended it, but if you have any other suggestion for doing this, it will be welcomed -- http://mail.python.org/mailman/listinfo/python-list
Re: Tweepy: Invalid arguments at function call (tweepy.Stream()) (Terry Reedy)
Thanks a lot for your answer. I'm using python 2.7.2 and tweetpy 1.7 >>> help(tweepy) Help on package tweepy: NAME tweepy - Tweepy Twitter API library (...) VERSION 1.7.1 and probably that is the problem, the link that you gave me refers to the 1.2 version page... Anyway, i already have their IRC direction and i think it would be easier to find support there. Thanks again. Ricardo Mansilla ps: sometimes i get lazy about writing the whole link to a precise direction which lacks of importance in my point; please, don't judge me for my exquisite way of keep the attention in the correct place... :) -- http://mail.python.org/mailman/listinfo/python-list
Does py2app improves speed?
Hi everyone.. My question is exactly as in the subject of This Mail. I have made a Python script which is to slow and i have heard (and common sense also suggest) that if you use some libraries to "frozen" the script the performance improves substantially. So I need to know; is This a myth or it is a fact? Thanks in advance for your time. -- http://mail.python.org/mailman/listinfo/python-list
Re: Does py2app improves speed?
Well, that's sad... I think Im gonna end getting back to C++ for This. But anyway, thanks a lot for the quick answer... Bye. -- http://mail.python.org/mailman/listinfo/python-list
Re: Does py2app improves speed?
Most of méthods for improving the speed are related to efficient memory management and using specific structures for a specific tasks... But i have already optimized my code (which is very short actually) following all these rules and it is very slow yet. Do you think there is another way to do This? Probably i'm missing something here... On 24/11/2011, at 07:38, Dave Angel wrote: > On 11/24/2011 08:26 AM, Ricardo Mansilla wrote: >> Well, that's sad...
