向我解释尾调用优化有什么大不了的，以及为什么 Python 需要它 [英] Explain to me what the big deal with tail call optimization is and why Python needs it
问题描述
很明显，关于 Python 是否需要尾调用优化的问题引起了很大争议.当有人向 Guido 发送了一份 SICP 因为他没有明白".我和圭多在同一条船上.我理解尾调用优化的概念.我实在想不出为什么 Python 真的需要它.
So apparently, there's been a big brouhaha over whether or not Python needs tail call optimization. This came to a head when someone shipped Guido a copy of SICP because he didn't "get it." I'm in the same boat as Guido. I understand the concept of tail call optimization. I just can't think of any reason why Python really needs it.
为了让我更容易理解，谁能给我一段代码，使用 TCO 可以大大简化?
To make this easier for me to understand, could someone give me a snippet of code that would be greatly simplified using TCO?
推荐答案
就我个人而言，我非常重视尾调用优化；但主要是因为它使递归与迭代一样有效(或使迭代成为递归的子集).在极简语言中，您可以在不牺牲性能的情况下获得强大的表达能力.
Personally, I put great value on tail call optimization; but mainly because it makes recursion as efficient as iteration (or makes iteration a subset of recursion). In minimalistic languages you get huge expressive power without sacrificing performance.
在实用"语言(如 Python)中，OTOH，对于几乎所有可以想象的情况，您通常都有很多其他结构，因此它不那么重要.拥有它总是一件好事，当然，允许出现不可预见的情况.
In a 'practical' language (like Python), OTOH, you usually have a lot of other constructions for almost every situation imaginable, so it's less critical. It is always a good thing to have, to allow for unforeseen situations, of course.
