import string

def numwords(s):
    list = string.split(s)
    return len(list)

inp = open("menu.txt","r")
total = 0

for line in inp.readlines():
    total =  total + numwords(line)

print "File had %d words" % total

inp.close()

Ex2：Counting Word、Lines 、Characters

import string, sys

if len(sys.argv) != 2:
    name = raw_input("Enter the file name: ")

inp = open(name,"r")

words = 0
lines = 0
chars = 0

for line in inp.readlines():
    lines = lines + 1

list = string.split(line)
words = words + len(list)
chars = len(line)
print "%s has %s lines, %d words and %d characters" % (name,lines,words,chars)
inp.close()
