Question

我想在python中附加一个字符串列表，如下所示：

messages = ["hello","hi"]

预期输出

messages = ["hello","hi","bye"]

她是一个我有错误的例子：

＆＃34; str对象没有属性＆＃34;追加＆＃34; ＆＃34;

messages = ["really","hey"]
user = ["0.0.0.0"]
serv.bind(('0.0.0.0',12800))
msg, addr = serv.recvfrom(1024)
msg = msg.decode()
user.append(addr)
messages.append(msg)

完整代码：

chat = ['Bienvenu dans le chat de Dungeons !','Welcome on Dungeon\'s chat']
user = ["really","hey"]
pseudo = ["foo","this"]
isConnect = [0]



serv = socket.socket(socket.AF_INET,socket.SOCK_DGRAM)
user_tab = 0

serv.bind(('0.0.0.0',12800))



while(1):

    msg, addr = serv.recvfrom(1024)
    msg = msg.decode()

    if (msg.find("[pseudo]")!=-1):
        firstPlace = msg.find("[pseudo]")
        secondPlace = msg.find("[pswd]")
        if firstPlace != -1 and secondPlace != -1:
            pseu = msg[firstPlace+9:secondPlace]
            pswd = msg[secondPlace+7:]
            print("New client with infos ip ",addr, ",pseudo", pseu, "and password", pswd)
            user.append(addr)
            pseudo.append(pseu)
            isConnect.append("1")
            send_connect="connect"
            serv.sendto(send_connect.encode(),addr)

Answer 1

>>> l = ["hello","hi"]
>>> l.append("bye")
>>> l
['hello', 'hi', 'bye']

Answer 2

我找到了解决方案，但我真的不明白。这是我改变的：

pseu = str(msg[firstPlace+9:secondPlace])
