Building a Web Client in Python

To ensure that you have all the lines needed for this program, here is the code for this web client.

#!/usr/bin/env python

# import sys for handling command line argument
# import socket for network communications
import sys, socket

# hard-wire the port number for safety's sake
# then take the names of the host and file from the command line
port = 80
host = sys.argv[1]
filename = sys.argv[2]

# create a socket object called 'c'
c = socket.socket(socket.AF_INET, socket.SOCK_STREAM)

# connect to the socket
c.connect((host, port))

# create a file-like object to read
fileobj = c.makefile('r', 0)

# Ask the server for the file
fileobj.write("GET "+filename+" HTTP/1.0\n\n")

# read the lines of the file object into a buffer, buff
buff = fileobj.readlines()

# step through the buffer, printing each line
for line in buff:
     print line
