How to paste source code to vim without error format?

Question

When I copy a python code, and paste to vim. the indents are all error. but I paste into emacs or gedit, it is right.

that is difficult to describle, let's see the screenshot. Notice:the blue and yellow line is just use the "indent guides plugin".

This is the source code example:

import threading import time class timer(threading.Thread): #The timer class is derived from the class threading.Thread     def __init__(self, num, interval):         threading.Thread.__init__(self)         self.thread_num = num         self.interval = interval         self.thread_stop = False      def run(self): #Overwrite run() method, put what you want the thread do here         while not self.thread_stop:             print 'Thread Object(%d), Time:%s/n' %(self.thread_num, time.ctime())             time.sleep(self.interval)     def stop(self):         self.thread_stop = True   def test():     thread1 = timer(1, 1)     thread2 = timer(2, 2)     thread1.start()     thread2.start()     time.sleep(10)     thread1.stop()     thread2.stop()     return  if __name__ == '__main__':     test()

Automatic indenting kicked in.

The easiest way to disable it is: :set paste

:help paste  'paste'                 boolean (default off)                               global                         {not in Vi}     Put Vim in Paste mode.  This is useful if you want to cut or copy     some text from one window and paste it in Vim.  This will avoid     unexpected effects.     Setting this option is useful when using Vim in a terminal, where Vim     cannot distinguish between typed text and pasted text.  In the GUI, Vim     knows about pasting and will mostly do the right thing without 'paste'     being set.  The same is true for a terminal where Vim handles the     mouse clicks itself.
