Python package name duplication
问题
假设在PyPI中有一个名为pkg_1的包。那么名称为pkg__1、pkg.1或pkg-1的包可以上传到PyPI吗？
这里提到：
名称是您的包的分发名称。只要它只包含字母、数字、
.、_和-，它可以是任何名称。
但是这里提到：
在根URL下面，每个单独的项目都有另一个URL。此URL的格式是
/<project>/，其中<project>由该项目的规范化名称替代，因此名为“HolyGrail”的项目将具有类似/holygrail/的URL。
而通过规范化名称，它的意思是：
名称应全部小写，所有字符
.、-或_的运行都应替换为单个-字符。
所以我猜一个名为a_.-b的包被视为与a-b相同。我对吗？
英文:
Suppose there is a package named pkg_1 in PyPI. Can packages with names pkg__1, pkg.1 or pkg-1 be uploaded to PyPI?
Here mentioned:
> name is the distribution name of your package. This can be any name as
> long as it only contains letters, numbers, ., _ , and -.
But Here mentioned:
> Below the root URL is another URL for each individual project
> contained within a repository. The format of this URL is /<project>/
> where the <project> is replaced by the normalized name for that
> project, so a project named “HolyGrail” would have a URL like
> /holygrail/.
And by the normalized name, it means:
> The name should be lowercased with all runs of the characters ., -, or _ replaced with a single - character.
So I guess a package named a_.-b is considered the same as a-b. Am I right?

我建议使用packaging.utils.canonicalize_name() 实用函数，这是第三方 packaging 库中的函数，该库是 pip 本身用于此类工作的库。
from packaging.utils import canonicalize_name
names = [
'pkg-1',
'pkg__1',
'pkg.1',
'Pkg_-.1',
]
for name in names:
print(f"{name=}: {canonicalize_name(name)}")
name='pkg-1': pkg-1
name='pkg__1': pkg-1
name='pkg.1': pkg-1
name='Pkg_-.1': pkg-1
英文:
I recommend using the packaging.utils.canonicalize_name() utility function from the 3rd party packaging library which is the library used by pip itself for this kind of work.
from packaging.utils import canonicalize_name
names = [
'pkg-1',
'pkg__1',
'pkg.1',
'Pkg_-.1',
]
for name in names:
print(f"{name=}: {canonicalize_name(name)}")
name='pkg-1': pkg-1
name='pkg__1': pkg-1
name='pkg.1': pkg-1
name='Pkg_-.1': pkg-1
