python统计文本文件内单词数量

# 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)

    # word total count
    words += len(tempwords)
