如何更改元组中的值? [英] How to change values in a tuple?

问题描述

我有一个名为 values 的元组，它包含以下内容:

I have a tuple called values which contains the following:

('275', '54000', '0.0', '5000.0', '0.0')

我想更改此元组中的第一个值(即 275)，但我知道元组是不可变的，因此 values[0] = 200 将不起作用.我怎样才能做到这一点?

I want to change the first value (i.e., 275) in this tuple but I understand that tuples are immutable so values[0] = 200 will not work. How can I achieve this?

推荐答案

首先你需要问，你为什么要这样做?

First you need to ask, why you want to do this?

但可以通过:

t = ('275', '54000', '0.0', '5000.0', '0.0')
lst = list(t)
lst[0] = '300'
t = tuple(lst)

但是如果您需要更改某些内容，最好将其保留为 list

But if you're going to need to change things, you probably are better off keeping it as a list
