‘贰’ 利用Python列出最频繁的单词和它们的出现次数

Python2.7上测试通过

importurllib2
importre
fromcollectionsimportCounter
defget_data(url):
resp=urllib2.urlopen(url).read().lower()
returnresp
defanalyse(text,n=1):
'''showthenmostcommonwordsintext'''
res=Counter(re.split(r'W+',text,flags=re.M)).most_common(n)
print('words	times')
print('
'.join([k+'	'+str(v)fork,vinres]))
defmain():
data=get_data('http://www.umich.e/~umfandsf/other/ebooks/alice30.txt')
analyse(data,10)
main()

结果是
