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('!') &
