Python中的set函數(shù)用于創(chuàng)建一個無序且唯一的集合。以下是使用set函數(shù)的最佳實踐:
my_list = [1, 2, 2, 3, 4, 4, 5]
unique_set = set(my_list)
print(unique_set)
my_set = {1, 2, 3, 4, 5}
if 3 in my_set:
print("3存在于集合中")
set1 = {1, 2, 3, 4, 5}
set2 = {4, 5, 6, 7, 8}
union_set = set1.union(set2)
intersection_set = set1.intersection(set2)
difference_set = set1.difference(set2)
my_list = [1, 2, 3, 4, 5]
my_set = set(my_list)
if 3 in my_set:
print("3存在于集合中")
總的來說,set函數(shù)是一個非常有用的工具,可以用于去除重復(fù)元素、快速查找元素、進行集合運算等操作。
