python判斷集合的方法有哪些?

1、isdisjoint方法用于判斷兩個集合是否存在相同元素，沒有返回True，否則返回False。

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

my_set2={"banana","watermelon"}

#兩個集合沒有相同元素

ret_bool=my_set1.isdisjoint(my_set2)

print(ret_bool)#返回True

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

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

#兩個集合有相同元素

ret_bool=my_set1.isdisjoint(my_set2)

print(ret_bool)

2、issubset該方法用于判斷一個集合是否是另一個集合的子集，確定是返回True，否則返回False。

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

my_set2={"banana","watermelon"}

#第二個集合不是第一個集合的子集

ret_bool=my_set2.issubset(my_set1)

print(ret_bool)#返回False

#第二個集合是第一個集合的子集

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

my_set2={"orange","apple"}

ret_bool=my_set2.issubset(my_set1)

print(ret_bool)#返回True
