python-Tkinter文档与PEP8矛盾

PEP 8 states

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,official documentation是矛盾的：

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

import tkinter

Or, more often:

 from tkinter import *

这是“文档错误”吗？

解决方法:

我在这一点上提出了错误issue 32830,并且(Python核心开发人员达成的共识)是,尽管from tkinter import *确实违反了PEP 8,但这是一个合理的例外,因为tkinter“提供了大量名称(主要是常量,例如RIGHT或垂直),无需前缀即可使用.”此外,PEP 8声明“不要为了遵守此PEP而破坏向后兼容性！”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.
