Simple python program to create a localhost web server.

LocalWebserver.py

from socket import *

import sys 

serverSocket = socket(AF_INET, SOCK_STREAM) 
serverSocket.bind(('127.0.0.1',6789))

while True:
	serverSocket.listen(5)
	print('Ready to serve...') 
	connectionSocket, addr = serverSocket.accept()
  
	try:
		message = connectionSocket.recv(1024).decode()
		filename = message.split()[1]
		f = open(filename[1:])
		outputdata = f.read()
    
		connectionSocket.send("HTTP/1.1 200 OK\r\n".encode())
		connectionSocket.send(message.encode())
    
		for i in range(0, len(outputdata)):
			connectionSocket.send(outputdata[i].encode())
		connectionSocket.close()

	except IOError:
		connectionSocket.send("HTTP/1.1 404 Not Found\r\n".encode())
		connectionSocket.close()

serverSocket.close()

sys.exit()
