I been stuck on this problem for hours and I simply cannot get it to work. I am trying to run this python code to display the contents of HelloWorld.html on my localhost browser. 
The line 
f = open(filename[1:])
is getting me the error: 
UnicodeDecodeError: 'utf-8' codec can't decode byte 0xf7 in position 1: invalid start byte

#import socket module

from socket import *

import sys # In order to terminate the program

serverSocket = socket(AF_INET, SOCK_STREAM)

#Prepare a sever socket

# Binding our socket to the port
serverSocket.bind(('', 80))

while True:
    # establish the connection
    print('Ready to serve...')
    connectionSocket,addr = serverSocket.accept()
        message = connectionSocket.recv(1024)
        filename = message.split()[1]
        f = open(filename[1:])
        #Send one HTTP header line into socket
        connectionSocket.send(b'HTTP/1.0 200 OK\r\n\r\n')
        #Send the content of the request file to the client
        for i in range(0, len(outputdata)):

    except IOError:
    #Send response message for file not found
        connectionSocket.send(b'404 file Not Found')
    #Close client socket

sys.exit() #Terminating program after sending corresponding data
