Question

只是想获得给定模块的包名，为什么dunder 包属性不起作用？

import sys, inspect, os, numpy as np
print("The os package name is " + os.__package__)
print("The np package name is " + np.__package__)
print("The inspect package name is " + inspect.__package__)
print("The sys package name is " + sys.__package__)

我从上面得到的内容如下：

The os package name is 
The np package name is numpy
The inspect package name is 
The sys package name is

正如您所看到的，它仅适用于numpy，不适用于其他人。有人可以开导我为什么？我错过了什么？
