Python Set isdisjoint()用法及代碼示例

Python set isdisjoint() 函數檢查兩個集合是否不相交，如果不相交則返回 True，否則返回 False。當兩個集合的交集為空時，它們被稱為不相交。

Python設置isdisjoint()方法用法:

用法：set1.isdisjoint(set2)

參數：

另一組進行比較
或者
可迭代(列表、元組、字典和字符串)

返回：bool

Python 設置isdisjoint() 方法示例：

Python3


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

輸出：

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))

輸出：

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

示例 2：使用其他可迭代對象作為參數的 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))

輸出：

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

示例 3：兩個集合都是空的

在這裏，我們將看到如果我們使用 isdisjoint() 方法並且兩個集合均為空，將會輸出什麽。

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))

輸出

True
