TypeError: recv_thread() argument after * must be an iterable, not socket

错误

TypeError: recv_thread() argument after * must be an iterable, not socket的问题。

原因

这个错误是由于在创建一个线程时，将socket对象作为args参数传递给了recv_thread函数，而args参数需要一个可迭代的对象，比如元组或列表。

解决办法

可以通过在socket对象后面加一个逗号，将其转换为一个元组，来解决这个问题。代码是这样的：

def recv_thread(sock):
    while True:
        data = sock.recv(1024).decode()

thread = threading.Thread(target=recv_thread, args=(s))

可以改为：

def recv_thread(sock):
    while True:
        data = sock.recv(1024).decode()
        
thread = threading.Thread(target=recv_thread, args=(s,))

这样就可以避免TypeError: recv_thread() argument after * must be an iterable, not socket的错误了。
