如何在python中获取接收到的数据包的字节大小？

import socket

sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)

sock.bind(('0.0.0.0', 8080))

sock.listen(1)

conn, addr = sock.accept()
data = conn.recv(1024)

data_size = len(data)

import socket

sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
sock.bind(('0.0.0.0', 8080))
sock.listen(1)

conn, addr = sock.accept()
data = conn.recv(1024)
data_size = len(data)

print("Received data size:", data_size)
