How to append a list of strings

Question

I would like to append a list of string in python as below:

messages = ["hello","hi"]

Expected output

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

Her is an example where i do have an error :

"str object has no attribute "append" "

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)

Full code :

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)

Do not name your variable `list` or any other Python types or keywords. — Cory Kramer, Jul 16 '15 at 23:02
Look over the [official Python tutorial](https://docs.python.org/3.4/tutorial). — TigerhawkT3, Jul 16 '15 at 23:03
@Xavier59 you **will not** get the error you indicate in your question with the code in your question. Period. Are you sure you are running that **exact** code? — MattDMo, Jul 16 '15 at 23:24
Actually it is working 1-2 times but then, doing this error. I can't understand why — AnonBird, Jul 16 '15 at 23:32

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

No you don't, I just showed you that it works. If you are writing code that is producing errors, post a question that shows your **actual code** and the **full error message** that you are getting. – Cory Kramer Jul 16 '15 at 23:04

I found the solution, but i don't really understand it. Here is what I changed :

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