我可以有条件地选择要赋值的变量吗? [英] Can I conditionally choose what variable I assign a value to?

问题描述

我知道你可以在 Python 中做这样的事情:

I know that you can do things like this in Python:

var = value1 if( booleanCheck() ) else value2

我想知道的是，我是否可以有条件地选择将值放入具有类似结构的变量中?

What I want to know is if I can conditionally choose which var I place a value into with a similar sort of structure?

像这样:

(var1 if( booleanCheck() ) else var2) = value

特别是在我的情况下，我试图将一个子节点分配到二叉搜索树的正确一侧，我知道我可以做一个普通的 if 块，但我试图挑战自己使用最小的空间.

In my case specifically I'm trying to assign a child node to the correct side in a Binary Search Tree, I know I can just do a normal if block but I was trying to challenge myself to using minimal space.

推荐答案

理论上你可以这样做，如果两个变量都已经定义:

Well theoretically you could do something like this, if both variables are already defined:

var1, var2 = (value, var2) if booleanCheck() else (var1, value)

虽然不是说你应该这样做.

Not saying that you should do it, though.
