python统计文本文件内单词数量的方法_Python

本文实例讲述了python 统计文本文件内单词数量的方法。分享给大家供大家参考。具体实现方法如下：

									# count lines, sentences, and words of a text file

									# set all the counters to zero

									lines, blanklines, sentences, words = 0, 0, 0, 0

									print '-' * 50

									try:

									 # use a text file you have, or google for this one ...

									 filename = 'GettysburgAddress.txt'

									 textf = open(filename, 'r')

									except IOError:

									 print 'Cannot open file %s for reading' % filename

									 import sys

									 sys.exit(0)

									# reads one line at a time

									for line in textf:

									 print line,  # test

									 lines += 1

									 if line.startswith('\n'):

									  blanklines += 1

									 else:

									  # assume that each sentence ends with . or ! or ?

									  # so simply count these characters

									  sentences += line.count('.') + line.count('!') + line.count('?')

									  # create a list of words

									  # use None to split at any whitespace regardless of length

									  # so for instance double space counts as one space

									  tempwords = line.split(None)

									  print tempwords # test

									  # word total count

									  words += len(tempwords)

									textf.close()

									print '-' * 50

									print "Lines   : ", lines

									print "Blank lines: ", blanklines

									print "Sentences : ", sentences

									print "Words   : ", words

									# optional console wait for keypress

									from msvcrt import getch

									getch()
