 　　本文實例講述了python統計文本文件內單詞數量的方法。分享給大家供大家參考。具體實現方法如下：

　　?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 # 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()
