Python compares differences between two lists, same (difference set, intersection, and set)

Initializing data

listA = [‘zhangsan‘, ‘lisi‘, ‘wangwu‘]listB = [‘zhangsan‘, ‘lisi‘, ‘zhaoliu‘]

1, take the difference set
1.1, Lista corresponding to LISTB difference set

set(listA).difference(set(listB))-----set([‘wangwu‘])

1.2、listB对应listB的差集

set(listB).difference(set(listA))-----set([‘zhaoliu‘])

2, take the intersection

set(listA).intersection(set(listB))-----set([‘lisi‘, ‘zhangsan‘])

3. Take and set

set(listA).union(set(listB))-----set([‘lisi‘, ‘zhaoliu‘, ‘zhangsan‘, ‘wangwu‘])

For more usage, you can check the usage of the set yourself.
