Today, I'll introduce how to use asynchronous programming in Python. This article focuses on the usage of asynchronous programming, so it won't delve too much into underlying concepts.

Brief Introduction to Concepts

• Coroutine: A special function marked with async that can execute code asynchronously.
• Event Loop: The core of Python asynchronous programming, responsible for scheduling coroutines.
• Future: A low-level object representing the eventual result of an asynchronous operation.
• Task: A wrapper for Future that can encapsulate coroutines and supports operations like cancellation.

Variance is a concept in programming that is prone to mistakes. I used to have only a vague understanding of it, so this time I specifically looked up a lot of information online to thoroughly study the issue. I also took the opportunity to write a blog post introducing it, so that if I forget in the future, I can quickly recall it.

Friends who often install operating systems should be very familiar with making bootable drives, as it is a necessary step every time an operating system is installed. If the operating system to be installed is different from the previous one, then the bootable drive has to be made again.

Is there any tool that can get this job done once and for all, thus bidding farewell to the complicated steps of making a bootable drive? There really is such a tool, which is the "bootable drive making magic tool Ventoy" to be introduced in this article!
