如何在不使用“|"的情况下将两组连接在一行中

问题描述

假设 S 和 T 被分配了集合.如果不使用连接运算符 |，我如何找到这两个集合的并集?例如，这会找到交集:

Assume that S and T are assigned sets. Without using the join operator |, how can I find the union of the two sets? This, for example, finds the intersection: 

S = {1, 2, 3, 4}
T = {3, 4, 5, 6}
S_intersect_T = { i for i in S if i in T }

那么如何在不使用 | 的情况下在一行中找到两个集合的并集?

So how can I find the union of two sets in one line without using |?

解决方案

集合可以使用union方法:set.union(other_set)

You can use union method for sets: set.union(other_set)

请注意，它返回一个新集合，即它不会自行修改.

Note that it returns a new set i.e it doesn't modify itself.
