python两个list中怎么取交集，并集和差集

> a = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10] 
> b = [2, 5, 8, 11, 0]
> 
> 
> #取两个list的交集:jiaoji 
> jiaoji = list(set(a).intersection(set(b))) 
> print(jiaoji)


> #取两个list的交集:bingji 
> bingji = list(set(a).union(set(b))) 
> print(bingji)


> #取a和b之间的差集:chaji 
> chaji = list(set(a).difference(set(b))) 
> print(chaji)
