I am working with sockets. I have written code for python server which will receive data from a c# client and will display it in the console. The data may be an image or a text. Now problem is that how to differentiate between image and text because text must be displayed in the console and image has to save on the disk.

What I have tried:

Following is the python server code:

import socket
import os
import io
import os.path

class MyTCPHandler(socketserver.BaseRequestHandler):
    def handle(self):
        self.data=self.request.recv(1024).strip()
        print ("{} wrote:".format(self.client_address[0]))
        if os.path.isfile("image.png"):
            os.remove("image.png")

        file = open("image.png", "wb")
        while True:
            data = self.request.recv(1024)
            if not data:
                break
            file.write(data)
            print(str(list(data)))

        print("Done.")
        print (self.data)
        self.request.sendall(self.data.upper())

if __name__ == "__main__":
    HOST, PORT = socket.gethostname(), 11000
    print ("IP: "+socket.gethostbyname('BlackZero-PC'))
    print ("Host: "+socket.gethostname())

    server=socketserver.TCPServer((HOST, PORT), MyTCPHandler)
    server.serve_forever()
