Python重新加载模块

from imp import reload

reload(模块名)#重新载入模块,前提是模块已经导入

Python socket实现简单web服务器

import socket

def service_client(new_socket):
    try:
        request = new_socket.recv(1024)
        print(request)
        response = "HTTP/1.1 200 OK\r\n"
        response += "\r\n"
        response += "tcp_socket"
        new_socket.send(response.encode("utf-8"))
        new_socket.close()
    except:
        new_socket.close()
def main():
    tcp_socket = socket.socket(socket.AF_INET,socket.SOCK_STREAM)
    tcp_socket.setsockopt(socket.SOL_SOCKET,socket.SO_REUSEADDR,1)
    tcp_socket.bind(("",80))
    tcp_socket.listen(128)
    while True:
        new_socket,client_add = tcp_socket.accept()
        service_client(new_socket)
    tcp_socket.close()

if __name__ == '__main__':
    main()
