pythonrecvfrom阻塞

Ⅰ python設計UDP通信時，recvfrom()中的參數是什麼意思

socket.recvfrom(bufsize[, flags])

Receive data from the socket. The return value is a pair (bytes, address) where bytes is a bytes object
representing the data received and address is the address of the socket
sending the data. See the Unix manual page recv(2) for
the meaning of the optional argument flags; it defaults to zero. (The
format of address depends on the address family — see above.)

recvfrom(1)就是從緩沖區讀一個位元組的數據
