python reprlib
Pythonreprlib是Python内置模块之一，它提供了一个定制化的版本的repr()函数，主要用于生成对象的可打印表示形式。与标准库中的repr()不同，Pythonreprlib对于输出非常长的字符串或者嵌套深度很大的数据结构时，会进行截断处理，以保证输出结果的可读性。

以下是一个简单的示例：

python
import reprlib

long_string = "This is a very long string that goes on and on for miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles and miles
