列表比较 列表比较需要引入operator模块的eq方法。 import operator name=["校长","主任","班主任"] list1=["李华",'English',150] list3=["李华",'English',150] list2=["小明","China",200] print("operator.eq(name,list1,):",operator.eq(name,list1)) print("operator.eq(name,list2,):",o...
请注意:union(), intersection(), difference() 和 symmetric_difference() 的非运算符(non-operator,就是形如 s.union()这样的)版本将会接受任何 iterable 作为参数。相反,它们的运算符版本(operator based counterparts)要求参数必须是 sets,如果都是set会报错。 In [29]: set('abc') & 'cbs' --- TypeErr...
B.difference(A) - returns a set with elements unique to set B Note: Mathematically, the operation A.difference(B) is equivalent to A - B. Example 2: Set Difference Using - Operator We can also find the set difference using - operator in Python. For example, A = {'a', 'b', 'c...

In the above example, we have used the ^ operator to find the symmetric difference of A and B and A, B and C. With ^ operator, we can also find the symmetric difference of 3 sets. Also Read: Python Set difference() Python Set symmetric_difference_update() Before...
