多线程并发练习（Day35）

练习一

def action(conn):
    while True:

        print(data)
        conn.send(data.upper())

if __name__ == '__main__':

    while True:
        conn,addr=s.accept()

        p=threading.Thread(target=action,args=(conn,))

练习二：

三个任务，一个是接收用户输入，一个将用户输入的内容格式化成大写，一个将格式化后的结果存入文件

 from threading import Thread
 msg_l=[]
 format_l=[]
 def talk():
     while True:
         msg=input('>>: ').strip()
         if not msg:continue
         msg_l.append(msg)

 def format_msg():
     while True:
         if msg_l:
             res=msg_l.pop()
             format_l.append(res.upper())

 def save():
     while True:
         if format_l:
             with open('db.txt','a',encoding='utf-8') as f:
                 res=format_l.pop()
                 f.write('%s\n' %res)

 if __name__ == '__main__':
     t1=Thread(target=talk)
     t2=Thread(target=format_msg)
     t3=Thread(target=save)
     t1.start()
     t2.start()
     t3.start()
