属于类def my_function()的一部分，它本身是模块class MyClass()的一部分，它是包mymodule.py的一部分。< / p>
mypackage在科学手稿中，我想以最短和最精确的方式引用函数mypackage/
mypackage/mymodule.py
user$ cat mypackage/mymodule.py
#class MyClass(object):
# def my_function(self):
# ...
，同时提供此函数所在的包，模块和类的信息。
因此，建议将其称为：my_function？
（相比之下，在mypackage.mymodule.MyClass.my_function()中，通常将特定函数称为R。）
