python判斷集合的方法有哪些?
1、isdisjoint方法用于判斷兩個(gè)集合是否存在相同元素，沒(méi)有返回True，否則返回False。
my_set1={"apple","orange","pear","grape"}
my_set2={"banana","watermelon"}
#兩個(gè)集合沒(méi)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(gè)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(gè)集合是否是另一個(gè)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(gè)集合不是第一個(gè)集合的子集
ret_bool=my_set2.issubset(my_set1)
print(ret_bool)#返回False
#第二個(gè)集合是第一個(gè)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
以上就是Python判斷集合的方法，希望能對(duì)大家有所幫助。更多Python學(xué)習(xí)教程請(qǐng)關(guān)注IT培訓(xùn)機(jī)構(gòu):千鋒教育。
