Question #
Python 函数中参数是如何传递的？是值传递还是引用传递？
Answer #
Python 的参数传递是赋值传递 （pass by assignment），或者叫作对象的引用传递（pass by object reference）。Python 里所有的数据类型都是对象，所以参数传递时，只是让新变量与原变量指向相同的对象而已，并不存在值传递或是引用传递一说。
“Remember that arguments are passed by assignment in Python. Since assignment just creates references to objects, there’s no alias between an argument name in the caller and callee, and so no call-by-reference per Se.”
