Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

◠ ◡ ◠ >> 在 python 中有泛型吗? 给我一个实例吧
在 Python 中,虽然没有像 TypeScript 或其他语言中的显式泛型支持,但可以通过使用"类型提示"和"typevar"来实现类似的泛型行为。下面是一个使用类型提示和"typevar"的示例:

    from typing import TypeVar, List
    
    T = TypeVar('T')  # 定义一个泛型类型变量
    
    def reverse_list(lst: List[T]) -> List[T]:
        return lst[::-1]
    
    # 使用泛型函数
    numbers = [1, 2, 3, 4, 5]
    reversed_numbers = reverse_list(numbers)
    print(reversed_numbers)  # 输出: [5, 4, 3, 2, 1]
    
    names = ["Alice", "Bob", "Charlie"]
    reversed_names = reverse_list(names)
    print(reversed_names)  # 输出: ["Charlie", "Bob", "Alice"]

在上面的示例中,T = TypeVar('T')创建了一个泛型类型变量T。然后,我们定义了一个名为reverse_list的函数,它接受一个列表(List)类型的参数lst,并返回一个相同类型的列表。函数内部使用[::-1]语法来反转列表的顺序。

通过将List[T]作为函数参数的类型提示,我们表明lst参数可以是任意类型的列表。这样,我们可以在函数调用时传递不同类型的列表,并得到正确的结果。

在上面的示例中,我们分别传递了一个整数列表和一个字符串列表,并成功地得到了反转后的列表。这展示了使用类型提示和"typevar"实现泛型函数的能力。
