in python, method resolution order (mro) refers to the order in which python searches for a method in a class hierarchy. this tutorial will explain the concept of mro and demonstrate how to get the mro of a class using python.
when you call a method on an object in python, the interpreter needs to determine which implementation of that method to use. this process is governed by the method resolution order. python uses the c3 linearization algorithm to compute the mro for a class.
the c3 linearization algorithm ensures that the method resolution order respects the following principles:
understanding the mro is crucial, especially when dealing with multiple inheritance in python, as it helps you predict how method lookups will behave.
python provides the mro() method to get the method resolution order of a class. this method returns a tuple that represents the order in which python will search for methods in the class hierarchy.
let's demonstrate how to get the mro of a class using an example.
in this example:
when we call mro() on class d, it returns the method resolution order. running this code will output:
this output indicates that when you call a method on an instance of class d, python will first look for the method in d, then in b, then in c, then in a, and finally in the base object class.
understanding the mro helps you predict how method lookups will behave, especially in complex inheritance hierarchies.
method resolution order (mro) is an important concept in python, especially when dealing with inheritance and method lookups. python provides the mro() method to get the method resolution order of a class, which helps in understanding the order in which methods will be searched for in the class hierarchy. this tutorial explained the concept of mro and demonstrated how to get the mro of a class using python.
