python在linux通过socket定义函数

客户机端

import socket

ip = "10.0.105.182" #服务器的
port = 5000 #对方的端口

c = socket.socket(socket.AF_INET,socket.SOCK_STREAM)
c.connect((ip,port))

def send_file():
    file = input("请输入要发送的文件：")
    filename = file.split("\\")[-1]
    print(filename)
    c.send(bytes(filename,encoding='utf8'))
    with open(file,"rb") as f:
        data = f.read()
        c.send(data)


def get_file():
    file = input("请输入你要下载的文件：")
    c.send(bytes(file,encoding="utf8"))
    filename = file.split("/")[-1]
    with open(filename,"wb") as f:
        f.write(c.recv(20000))


def send_common():
    while True:
        cmd = input("请输入命令：")
        c.send(bytes(cmd,encoding="utf8"))
        if cmd == "bye":
            break
        data = c.recv(1000)
        print(str(data,encoding="utf8"))

def main():
    while True:
        cmd = input("请输入，common，getfile，sendfile，byebye:")
        c.send(bytes(cmd,encoding="utf8"))
        if cmd == "byebye":
            break
        elif cmd == "common":
            send_common()
        elif cmd == "getfile":
            get_file()
        elif cmd == "sendfile":
            send_file()
        else:
            continue
    c.close()

if __name__ == "__main__":
    main()

服务器端
