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 zerolines, blanklines, sentences, words = 0, 0, 0, 0print '-' * 50try: # 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 timefor 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 '-' * 50print lines : , linesprint blank lines: , blanklinesprint sentences : , sentencesprint words : , words# optional console wait for keypressfrom msvcrt import getchgetch()
希望本文所述对大家的python程序设计有所帮助。
