Python Set isdisjoint()用法及代码示例

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，它们被称为不相交。

Python设置isdisjoint()方法用法:

用法：set1.isdisjoint(set2)

参数：

另一组进行比较
或者
可迭代(列表、元组、字典和字符串)

返回：bool

Python 设置isdisjoint() 方法示例：

Python3


s1 = {1, 2, 3}
s2 = {4, 5, 6}
print(s1.isdisjoint(s2))

输出：

True

示例 1：使用 Set isdisjoint() 方法

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：使用其他可迭代对象作为参数的 Python Set isdisjoint()

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: 'Orange'}
# Dictionary dict2
dict2 = {'Apple': 1, 'Orange': 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

示例 3：两个集合都是空的

在这里，我们将看到如果我们使用 isdisjoint() 方法并且两个集合均为空，将会输出什么。

Python3


# Python code to demonstrate
# isdisjoint method with blank
# sets
# defining empty set1
s1 = set()
# defining empty set2
s2 = set()
# using the isdisjoint method 
# with empty sets
print(s1.isdisjoint(s2))

输出

True
