Python Set isdisjoint()用法及代码示例

设置 isdisjoint() 方法

isdisjoint() 方法用于检查两个集合中的元素是否相同，以一个集合(通常称为这个集合)调用方法，并提供另一个集合作为参数，如果两个集合中没有一个元素是公共的，则方法返回 "True"设置，否则返回 "False"。

用法:

    set1.isdisjoint(set2)

参数：

• set1– 它代表了 set1(这个 set)。
• set2– 它代表 set2(另一个要比较的集合)。

返回值：

这个方法的返回类型是<class 'bool'>，它返回一个布尔值(真或假)。

范例1：

# Python Set isdisjoint() Method with Example

# declaring the sets
cars_1 = {"Porsche", "Audi", "Lexus"}
cars_2 = {"Porsche", "Mazda", "Lincoln"}
cars_3 = {"BMW", "Mazda", "Lincoln"}

# isdisjoint() method call
result = cars_1.isdisjoint(cars_2)
print("cars_1.isdisjoint(cars_2):", result)

result = cars_2.isdisjoint(cars_3)
print("cars_2.isdisjoint(cars_3):", result)

result = cars_1.isdisjoint(cars_3)
print("cars_1.isdisjoint(cars_3):", result)

输出

cars_1.isdisjoint(cars_2): False
cars_2.isdisjoint(cars_3): False
cars_1.isdisjoint(cars_3): True

范例2：

# Python Set isdisjoint() Method with Example

# declaring the sets
x = {"ABC", "PQR", "XYZ"}
y = {"ABC", "PQR", "XYZ"}
z = {"DEF", "MNO", "UVW"}

# isdisjoint() method calls
result = x.isdisjoint(y)
print("x.isdisjoint(y):", result)

result = y.isdisjoint(z)
print("y.isdisjoint(z):", result)

result = z.isdisjoint(x)
print("z.isdisjoint(x):", result)

result = x.isdisjoint(z)
print("x.isdisjoint(z):", result)

result = y.isdisjoint(x)
print("y.isdisjoint(x):", result)

输出

x.isdisjoint(y): False
y.isdisjoint(z): True
z.isdisjoint(x): True
x.isdisjoint(z): True
y.isdisjoint(x): False
