The document outlines a code snippet for constructing a basic Python web server using the socket module. It includes steps for establishing a server socket, accepting connections, reading requested files, and sending HTTP responses. It also notes error handling for when a requested file is not found.

1. Howdo I construct a pythonweb server usingthis code?
#import socket module
fromsocket import *
serverSocket = socket(AF_INET, SOCK_STREAM)
#Prepare a sever socket
#Fillinstart
#Fillinend
while True:
#Establishthe connection
print 'Readyto serve...'
connectionSocket, addr = #Fillinstart #Fillinend
try:
message = #Fillinstart #Fillinend
filename = message.split()[1]
f= open(filename[1:])
outputdata = #Fillinstart #Fillinend
#Send one HTTP header line into socket
#Fillinstart
#Fillinend
#Send the content ofthe requested file to the client
for iinrange(0, len(outputdata)):
connectionSocket.send(outputdata[i])
connectionSocket.close()
except IOError:
#Send response message for file not found
#Fillinstart
#Fillinend
#Close client socket
#Fillinstart
#Fillinend
serverSocket.close()
