Python并集是什么意思？

my_set1 = {"apple", "orange", "pear", "banana", "food"}

my_set2 = {"apple", "orange", "pear"}

both = my_set1 | my_set2

print(both)

使用 union 完成。

my_set1 = {"apple", "orange", "pear", "banana", "food"}

my_set2 = {"apple", "orange", "pear"}

both = my_set1.union(my_set2)

print(both)
