本文实例讲述了Python计算一个文件里字数的方法。分享给大家供大家参考。具体如下：
这段程序从所给文件中找出字数来。
from string import *
def countWords(s):
words=split(s)
return len(words)
#returns the number of words
filename=open("welcome.txt",'r')
#open an file in reading mode
total_words=0
for line in filename:
total_words=total_words + countWords(line)
#counts the total words
print total_words希望本文所述对大家的Python程序设计有所帮助。
