    recommend to use coroutine+muti process to replace muti thread in python

    basic:

    import time, threading
    
    # 新线程执行的代码:
    def loop():
        print 'thread %s is running...' % threading.current_thread().name
        n = 0
        while n < 5:
            n = n + 1
            print 'thread %s >>> %s' % (threading.current_thread().name, n)
            time.sleep(1)
        print 'thread %s ended.' % threading.current_thread().name
    
    print 'thread %s is running...' % threading.current_thread().name
    t = threading.Thread(target=loop, name='LoopThread')
    t.start()
    t.join()
    print 'thread %s ended.' % threading.current_thread().name

    lock:

    balance = 0
    lock = threading.Lock()
    
    def run_thread(n):
        for i in range(100000):
            # 先要获取锁:
            lock.acquire()
            try:
                # 放心地改吧:
                change_it(n)
            finally:
                # 改完了一定要释放锁:
                lock.release()

    arugments:

    import threading
    
    
    def some_func(one, two, an_arg = 0):
        return one + two * an_arg
    
    
    eg = threading.Thread(target=some_func,
                          args = (1, 2),
                          kwargs = {"an_arg": 3})
