Python isdisjoint()用法及代碼示例

當兩個集合的交集為空時，它們是不相交的。簡而言之，它們之間沒有任何共同的元素。

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)

參數：

isdisjoint()方法僅接受一個參數。它還可以對disjoint()進行迭代(列表，元組，字典和字符串)。 isdisjoint()方法將自動將可迭代對象轉換為集合，並檢查集合是否不相交。

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實現：

# 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
