问题描述
PEP 8
尽管如此，相互矛盾：
import tkinter
from tkinter import *
这是文档错误吗？
推荐答案
我提出了错误在这一点上（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.
