Python中的 isdisjoint()函数

Python set isdisjoint()函数检查两个集合是否不相交，如果不相交则返回True，否则返回False。当两个集合的交集为空时，我们称这两个集合是不相交的。简而言之，它们之间没有任何共同的元素。

例子：

Let set A = {2, 4, 5, 6}
and set B = {7, 8, 9, 10} 

集合 A 和集合 B 被称为不相交集合，因为它们的交集为空。它们之间没有任何共同的元素。

Python isdisjoint()语法

set1.isdisjoint(set2)

Python isdisjoint()参数

isdisjoint() Python方法只接受一个参数。它还可以将可迭代的（列表、元组、字典和字符串）用于 disjoint()。 isdisjoint() 方法会自动将可迭代对象转换为集合，并检查集合是否不相交。

Python isdisjoint()返回值

returns Trueif the two sets are disjoint. 
returns Falseif the twos sets are not disjoint.

Python设置 isdisjoint() 示例

示例 1：工作集 isdisjoin()

Python3

# Python3 program for isdisjoint() function
set1 = {2, 4, 5, 6}
set2 = {7, 8, 9, 10}
set3 = {1, 2}
 
# checking of disjoint of two sets
print("set1 and set2 are disjoint?",
      set1.isdisjoint(set2))
 
print("set1 and set3 are disjoint?",
      set1.isdisjoint(set3))

输出：

set1 and set2 are disjoint? True
set1 and set3 are disjoint? False

示例 2： Python isdisjoint() 与其他 Iterables 作为参数

Python3

# Set
A = {2, 4, 5, 6}
 
# List
lis = [1, 2, 3, 4, 5]
 
# Dictionary dict, Set is formed on Keys
dict = {1: 'Apple', 2: 'Orage'}
 
# Dictionary dict2
dict2 = {'Apple': 1, 'Orage': 2}
 
print("Set A and List lis disjoint?", A.isdisjoint(lis))
print("Set A and dict are disjoint?", A.isdisjoint(dict))
print("Set A and dict2 are disjoint?", A.isdisjoint(dict2))

输出：

Set A and List lis disjoint? False
Set A and dict are disjoint? False
Set A and dict2 are disjoint? True
