title: Getting AttributeError: 'int' object has no attribute 'start' when trying to run a basic thread program
body: <p>I'm new to threads and am executing a very basic thread example. The following is the program I'm trying to execute:</p>
  
  <pre><code>import os
  import thread
  import threading
  
  def main():
      t1=thread.start_new_thread(prints,(3,))
      t2=thread.start_new_thread(prints,(5,))
      t1.start()
      t2.start()
      #t1.join()
      #t2.join()
  
  def prints(i):
      while(i&gt;0):
          print "i="+str(i)+"\n"
          i=i-1
  
  if __name__=='__main__':
     main()
  </code></pre>
  
  <p>When I try and execute, I keep getting the following error (<strong>AttributeError: 'int' object has no attribute 'start'</strong>):</p>
  
  <pre><code>Traceback (most recent call last):
  i=3
    File "thread_1.py", line 19, in &lt;module&gt;
  
      i=2
  
  i=1
  main()
  
  i=5
  
  i=4
  
  i=3
  
  i=2
  
  i=1
  
    File "thread_1.py", line 8, in main
      t1.start()
  AttributeError: 'int' object has no attribute 'start'
  </code></pre>
  
  <p>As can be seen from the output, both are getting executed but not the way I was expecting it to (which is interleaved prints or something like that). It seems more sequential too. How can I modify/correct my program to get the expected output?</p>
