Python 统计一个纯英文文件中的单词总个数

import sys
import string 

if len(sys.argv) == 1 or sys.argv[1] in {"-h","--help"}:
	print ("usage: countWord.py filename_1 filename_2 ... finename_n")
	sys.exit()
else:
	count = 0
	strip = string.whitespace + string.punctuation + string.digits
	for filename in sys.argv[1:]:
		for line in open(filename):
			for word in line.split():
				word = word.strip(strip)
				count += 1

	print("the count of the file is {0} ...".format(count))
