Slice notation in Python is used for selecting a range of items from a sequence such as a list, tuple, or string. In this article, we’ll explore slice notation in detail and provide examples of how to use it in your Python code. By understanding slice notation, you’ll be able to w...
How Python is interpreted? By: Rajesh P.S.Python is an interpreted programming language, which means that the Python code is not compiled into machine code before execution. Instead, it is executed line by line by the Python interpreter. Here's how the interpretation process works: Source ...

从上面的内容可以看出,explain()能够提供大量与查询相关的信息。对于速度比较慢的查询来说,这是最重要的诊断工具之一。通过查看一个查询的explain()输出信息,可以知道查询使用了哪个索引,以及是如何使用的。对于任意查询,都可以在最后添加一个explain()调用(与调用sort()或者limit()一样,不过explain()必须放在最后)。
