title: Remove user from a tweet
body: <p>I have a python script which removes RT i.r retweet from the tweet, # hash tag.. Now I want to remove username as well i.e, a tweet which has @userxyz: i.e. @ symbol followed by username followed by :(colon).. I just want to remove such users: For example if the tweet is "@bugun: MHP’li Kemallettin Yılmaz Bank Asya'ya yapılan intihardır <a href="http://t.co/AKxMgMuuSs">http://t.co/AKxMgMuuSs</a> @bugun <a href="http://t.co/fyJbr098tw">http://t.co/fyJbr098tw</a>}" I want to remove @bugun: and get the result as "MHP’li Kemallettin Yılmaz Bank Asya'ya yapılan intihardır <a href="http://t.co/AKxMgMuuSs">http://t.co/AKxMgMuuSs</a> @bugun <a href="http://t.co/fyJbr098tw">http://t.co/fyJbr098tw</a>"</p>
  
  <p>Here is my code for hash and RT removal from the tweet:</p>
  
  <pre><code># coding:utf-8
  import sys, re
  x = open("test.txt", "r")
  for line in x:
      z = lambda line: re.compile('\#').sub('', re.compile('RT @').sub('@', line, count=1).strip())
      print z(line)
      saveFile = open("test_result.txt", "a")
      saveFile.write(z(line))
      saveFile.write("\n")
      saveFile.close()
  </code></pre>
