Python实现统计文本文件字数的方法_Python

本文实例讲述了Python实现统计文本文件字数的方法。分享给大家供大家参考，具体如下：

统计文本文件的字数，从当前目录下的file.txt取文件

									# -*- coding: GBK -*-

									import string

									import sys

									reload(sys)

									def compareItems((w1,c1), (w2,c2)):

									  if c1 > c2:

									    return - 1

									  elif c1 == c2:

									    return cmp(w1, w2)

									  else:

									    return 1

									def main():

									  fname = "file.txt"

									  try:

									    text = open(fname,'r').read()

									    text = string.lower(text)

									  except:

									    print "\nfile.txt is not exist!!! or There is a R/W error! "

									    sys.exit()

									  for ch in '!"#$%&()*+,-./:;<=>?@[\\]^_`{|}~':

									    text = string.replace(text, ch, ' ')

									  words = string.split(text)

									  counts = {}

									  for w in words:

									    counts[w] = counts.get(w,0) + 1

									  n = input("\n输入要统计的top单词数:")

									  items = counts.items()

									  items.sort(compareItems)

									  max = len(items)

									  print "\n单词总计:" + str(len(words))

									  print "单词净个数(已去重):" + str(max)

									  print "\n"

									  if n > max:

									    n = max

									  for i in range(n):

									    print "%-10s%5d" % items[i]

									if __name__ == '__main__':

									  main()

希望本文所述对大家Python程序设计有所帮助。
