python判断集合的方法有哪些?

1、isdisjoint方法用于判断两个集合是否存在相同元素，没有返回True，否则返回False。

my_set1={"apple","orange","pear","grape"}

my_set2={"banana","watermelon"}

#两个集合没有相同元素

ret_bool=my_set1.isdisjoint(my_set2)

print(ret_bool)#返回True

my_set1={"apple","orange","pear","grape"}

my_set2={"banana","watermelon","apple"}

#两个集合有相同元素

ret_bool=my_set1.isdisjoint(my_set2)

print(ret_bool)

2、issubset该方法用于判断一个集合是否是另一个集合的子集，确定是返回True，否则返回False。

my_set1={"apple","orange","pear","grape"}

my_set2={"banana","watermelon"}

#第二个集合不是第一个集合的子集

ret_bool=my_set2.issubset(my_set1)

print(ret_bool)#返回False

#第二个集合是第一个集合的子集

my_set1={"apple","orange","pear","grape"}

my_set2={"orange","apple"}

ret_bool=my_set2.issubset(my_set1)

print(ret_bool)#返回True
