Python客户端

Question

好的，我有一个连接到服务器的客户端，并且我想知道如何实现接收整个消息的方法，因为我不知道消息的大小。 （假设服务器向我发送了5000个字节（我事先不知道），而我创建的客户端仅接收1024个字节，我如何收集整个消息并将其与我收到的第一条消息连接起来？）

这发生在我身上

mensaje = cliente.recv(1024).decode() 
while (): #I don't know how to put the condition (it would be if the message had \ 0) (I don't know if python # has \ 0, to indicate the end of the string.
#In the event that if this is \ 0 in py, that would be the condition, you would have to put a for that
#recess the message until you find \ 0?. A for i in len (message): while i! = "\ 0"
      mensaje += cliente.recv(1024).decode()

我的另一个问题是遍历该消息，只是作为分隔符包含空格，我会使用.split，但是我的问题是：

for a in ...: #there is a way to put range (0, len (message.split (""))) (I know this doesn't work, #because I tried it and it gives me an error). I want to loop through the message and after doing the first # iteration compare to with a number or letter. But I don't really know how to do that for, I also # thought of two nested fors, but I don't know if it could overlap

为了更加清楚，我将其放在不加注释的位置：怀疑1.a：.py中没有“ \ 0”

mensaje = cliente.recv(1024).decode()
while .... :
      mensaje += cliente.recv(1024).decode()

疑问1.b：.py中有“ \ 0”

mensaje = cliente.recv(1024).decode()
for i in mensaje:
       while i != "\0":
              mensaje += cliente.recv(1024).decode()

疑问2：当我已经收到完整的消息时，我想遍历该消息，但它是一个字符串，以空格作为分隔符，并且我想计算最多x个符号的单词或数字

for i in range(0, len(mensaje,split(" "))): 

o
for i in range(0, len(mensaje)):
    for a in mensaje.split(" "):
         if a == x:
               ..............
         else:
               .............

我尝试这样做：

    cont=0
msg = cliente.recv(1024).decode()
    for i in msg:
        while i != "\0":
            msg += cliente.recv(1024).decode()


    for a in msg:
        for b in msg.split():
            if b == "x":
                break
            else:
                cont = cont + 1

但是它什么也没做，服务器也没有给我答案（它应该向我显示一些信息，为什么要发送计数器然后执行recv（1024）并打印消息。（但是什么都不显示）
