当然,如果定义了media属性值为all的screen . css,并将这个LINK放在它后面,打印样式就会继承所有屏幕样式。

如果一个非根用户在拥有所有能力的情况下运行这个程序,首先计算它的可继承集(pI)和 fI 的交集,所以缩减到只包含 cap_sys_admin。
If a non-root user runs this program while running with full capabilities, its inheritable set pI is first masked against fI so it is reduced to just cap_sys_admin.

An easy way to visualize how the dynamic typing works is to imagine a single base class called PyObject from which all other object types in Python inherit.
