Python中的isdisjoint()函数
在本文中,我们将学习如何在set()数据类型上实现isdisjoint()函数。此函数检查作为参数传递的集合是否具有任何共同的元素。如果找到任何元素,则返回False,否则返回True。
除了设置输入之外,isdisjoint()函数还可以将列表,元组和字典作为输入参数。THse类型由Python解释器隐式转换为集合类型。
语法
<set 1>.isdisjoint(<set 2>)
返回值
布尔值True/False
现在让我们考虑一个与实现有关的图示
示例
#declaration of the sample sets set_1 = {'t','u','t','o','r','i','a','l'} set_2 = {'p','o','i','n','t'} set_3 = {'p','y'} #checking of disjoint of two sets print("set1 and set2 are disjoint?", set_1.isdisjoint(set_2)) print("set2 and set3 are disjoint?", set_2.isdisjoint(set_3)) print("set1 and set3 are disjoint?", set_1.isdisjoint(set_3))
输出结果
set1 and set2 are disjoint? False set2 and set3 are disjoint? False set1 and set3 are disjoint? True
说明
由于set_1和set_2具有相同的元素,因此显示布尔值False。这与set_2和set_3之间的比较相同。但是在set_1和set_3之间的比较中,布尔值True会显示出来,因为找不到公共元素。
现在让我们看一下另一个涉及set类型之外的可迭代对象的图示。
注意:在外部声明的set_1必须是集合类型,以使解释器知道集合之间的比较。内部存在的参数可以是任何隐式转换为集合类型的类型。
示例
#declaration of the sample iterables set_1 = {'t','u','t','o','r','i','a','l'} set_2 = ('p','o','i','n','t') set_3 = {'p':'y'} set_4 = ['t','u','t','o','r','i','a','l'] #checking of disjoint of two sets print("set1 and set2 are disjoint?", set_1.isdisjoint(set_2)) print("set2 and set3 are disjoint?", set_1.isdisjoint(set_3)) print("set1 and set3 are disjoint?", set_1.isdisjoint(set_4))
输出结果
set1 and set2 are disjoint? False set2 and set3 are disjoint? True set1 and set3 are disjoint? False
在此还进行检查以找到共同的元素,并产生所需的输出。
结论
在本文中,我们学习了如何在Python中使用disjoint()函数以及借助该函数可以比较所有类型的参数。
