python统计字符串中每个单词出现的个数【一行】

s = ‘i am very very like you and like you‘

dict( [(i, s.split().count(i)) for i in s.split()] )
Out[2]: {‘i‘: 1, ‘am‘: 1, ‘very‘: 2, ‘like‘: 2, ‘you‘: 2, ‘and‘: 1}

set( map(lambda x:(x, s.split().count(x)), s.split()) )
Out[6]: {(‘am‘, 1), (‘and‘, 1), (‘i‘, 1), (‘like‘, 2), (‘very‘, 2), (‘you‘, 2)}

dict( map(lambda x:(x, s.split().count(x)), s.split()) )
Out[7]: {‘i‘: 1, ‘am‘: 1, ‘very‘: 2, ‘like‘: 2, ‘you‘: 2, ‘and‘: 1}
