python的坑

这个参考 https://blog.csdn.net/revilwang/article/details/37884127

============================

单个  tuplex 

============================

好比这个 这个会报错

threads = []
    for stock_name in stock_name_list:
        print(stock_name)
        th = threading.Thread(target=requestOneStock,args=(stock_name))
        threads.append(th)

TypeError: requestOneStock() takes 1 positional argument but 6 were given

缘由是单个元组 不是以（）来识别的 而是以逗号来识别的 因此要这么改

        th = threading.Thread(target=requestOneStock,args=(stock_name,))

就能够了
