ruby 标准库包含 PP(Pretty Print"的缩写)，它的结构格式比标准检查要好得多:

The ruby standard library contains PP (short for "Pretty Print"), which formats structures much better than the standard inspect:

您需要在源文件顶部require 'pp' 才能使用它，然后将p obj 替换为pp obj 在您的代码中.

You need to require 'pp' at the top of your source file before you can use it, and then just replace p obj with pp obj in your code.

我发现它特别适用于散列和数组！

I find it really useful for hashes and arrays in particular!
