整理一些對於集合基本操作供大家參考

list_1=[1,4,3,6,3,6,5,8]

print(list_1)

list_1 = set(list_1) #將列表轉換為集合，去同

list_2 = set([24,2,3,6,7])

print(list_1,list_2)

list_3 = list_1.intersection(list_2)#取兩個集合的交集(list_1 & list_2 )

print(list_3)

print(list_1.union(list_2)) #取並集(list_1 | list_2 )

list_4 = (list_1.difference(list_2))#求差集(list_1 - list_2 )

print(list_4)

print(list_2.difference(list_1))

print(list_1.symmetric_difference(list_2))#求對稱差集(list_1 ^ list_2 )

print(list_1.difference_update(list_2))
