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()
