Tkinter文档与PEP8相矛盾 [英] Tkinter documentation is contradicting PEP8

问题描述

PEP 8 状态

通配符导入（来自import *）应避免，因为它们不清楚名称空间中存在哪些名称，这会混淆读者和许多自动化工具。

Wildcard imports (from import *) should be avoided, as they make it unclear which names are present in the namespace, confusing both readers and many automated tools.

尽管如此，官方文档相互矛盾：

要使用Tkinter，您需要的只是一个简单的导入语句：

to use Tkinter all you need is a simple import statement:

import tkinter

或更常见的是：

Or, more often:

 from tkinter import *

这是文档错误吗？

推荐答案

我提出了错误问题32830 在这一点上（Python核心开发人员已达成共识）是，尽管 * 确实违反了PEP 8，但这是一个合理的例外，因为 tkinter 提供了大量易于使用的名称（主要是诸如RIGHT或VERTICAL之类的常量）没有前缀。此外，PEP 8声明不要为了遵守此PEP而破坏向后兼容性！而且由于tkinter目前经常以这种方式导入，因此这种观点在这里适用。

I raised bug issue 32830 on this point and the consensus (reached by Python core developers) is that although the from tkinter import * does violate PEP 8, this is a reasonable exception because tkinter "provides the enormous number of names (mostly constants like RIGHT or VERTICAL) which are convenient to use without prefix." Additionally, PEP 8 states "do not break backwards compatibility just to comply with this PEP!" and since tkinter is frequently imported in this way currently, this sentiment applies here.
