Python isdisjoint()用法及代码示例

当两个集合的交集为空时，它们是不相交的。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} 

set A and set B are said to be be disjoint sets as their
intersection is null. They do-not have any common elements in between them. 

用法:

set1.isdisjoint(set2)

参数：

isdisjoint()方法仅接受一个参数。它还可以对disjoint()进行迭代(列表，元组，字典和字符串)。 isdisjoint()方法将自动将可迭代对象转换为集合，并检查集合是否不相交。

返回值：

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

以下是上述方法的Python3实现：

# 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
