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()

希望本文所述对大家的python程序设计有所帮助。
