tweepy error python 2.7

Question

I keep getting this error:

tweepy.error.TweepError: [{u'message': u'Status is a duplicate.', u'code': 187

I have no clue why I am getting this error I have tried everything!

My main code is:

import socket
from urllib2 import urlopen, URLError, HTTPError

socket.setdefaulttimeout( 23 )  # timeout in seconds

url = 'http://google.co.uk'
try :
    response = urlopen( url )
except HTTPError, e:
    tweet_text = "Raspberry Pi Server is DOWN!"
    textfile = open('/root/Documents/server_check.txt','w')
    textfile.write("down")
    textfile.close()
except URLError, e:
    tweet_text = "Raspberry Pi Server is DOWN!"
    textfile = open('/root/Documents/server_check.txt','w')
    textfile.write("down")
    textfile.close()
else :
    textfile = open('/root/Documents/server_check.txt','r')
    if 'down' in open('/root/Documents/server_check.txt').read():
        tweet_text = "Raspberry Pi Server is UP!"
        textfile = open('/root/Documents/server_check.txt','w')
        textfile.write("up")
        textfile.close()
    elif 'up' in open('/root/Documents/server_check.txt').read():
        tweet_text = ""
if len(tweet_text) <= 140:
    if tweet_text == "Raspberry Pi Server is DOWN!" or tweet_text == "Raspberry Pi Server is UP!":
        api.update_status(status=tweet_text)
    else:
        pass
else:
    print "Your message is too long!"

I have removed the API's for security reasons! I have also removed the link to my server. Any help will be appreciated!

Thanks

The problem was that tweepy doesn't let you tweet the same tweet twice so to fix it i added these lines of code:

for status in tweepy.Cursor(api.user_timeline).items():
    try:
        api.destroy_status(status.id)
    except:
        pass

the code above deletes previous tweets so that my next tweet doesn't fail.

I hope this helps someone else!
