- n this assignment, you will develop a simple Web server in Python that is capableof processing only one request. Specifically, your Web server will(i) Create a connection socket when contacted by a client (browser)(ii) Receive the HTTP request from this connection(iii) Parse the request to determine the specific file being requested(iv) Get the requested file from the server’s file system(v) Create an HTTP response message consisting of the requested filepreceded by header lines(vi) Send the response over the TCP connection to the requesting browser.If a browser requests a file that is not present in your server, your server shouldreturn a “404 Not Found” error message.Your job is to code the steps above, run your server, and then test your server bysending requests from browsers running on different hosts. If you run your serveron a host that already has a Web server running on it, then you should use a differentport than port 80 for your Web server. Make sure to test your program…I have a server code: import socket # Define the server address and port server_address = ('localhost', 12345) # Create a TCP socket server_sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM) # Bind the socket to the server address server_sock.bind(server_address) # Listen for incoming connections server_sock.listen(1) while True: print('Waiting for a connection...') # Accept a client connection client_sock, client_address = server_sock.accept() print('Connected to:', client_address) try: # Receive data from the client data = client_sock.recv(1024) # Process the received data processed_data = data.swapcase() # Send the processed data back to the client client_sock.sendall(processed_data) finally: # Close the client socket client_sock.close() print('Connection closed.') break # Close the server socket server_sock.close() And the Client code: import…Can you run two client programs on a same host?

Reads in a list of hosts from a host file that is passed in as a parameter 2. Repeatedly, until the user selects quit (q), ask the user if the user wants to ping a host or look up a hosts DNS name 3. Once the user has selected an action, prompts the user for which host and then applies the action. Note that for the ssh action, the script must also ask the user for the user name that will be used to log into the host. Step 1 To accomplish step 1 above (reading in a list of hosts from a file), you will write a function called read_hosts. Functions in bash scripts have the following syntax: function name { # function body goes here } You can put any bash syntax inside the function as the function body. Also, note that the parameters to a function act like the parameters passed in at the command line. In other words, the parameters to the function are place in variable named $1, $2, and so on. So, how do you read the…
