Question

python中如何统计两个字典中相同单词数量有多少个？

Answer 1

>>> dictA={"a":1,"b":2,"c":3}
>>> dictB={"b":1,"c":2,"d":3}
>>> dict_temp={}
>>> for i in dictA:
dict_temp[i]=1
>>> for i in dictB:
dict_temp[i]=1
>>> duplicate_word_count=len(dictA)+len(dictB)-len(dict_temp)
>>> duplicate_word_count
2
>>>

Answer 2

len(set(dicA).difference(dicB))+len(set(dicB).difference(dicA))
