1 dzień temu · The operator module provides efficient functions that correspond to the intrinsic operators of Python, such as addition, comparison, and logical operations. Learn how to use these functions for object comparisons, mathematical operations, sequence operations, and more.
Learn how to use special methods to customize the behavior of operators for user-defined objects in Python. See examples of overloading arithmetic, comparison, and bitwise operators with classes and methods.
20 sty 2019 · 3 Answers. Sorted by: 459. You need to use the __getitem__ method. class MyClass: def __getitem__(self, key): return key * 2. myobj = MyClass() myobj[3] #Output: 6. And if you're going to be setting values you'll need to implement the __setitem__ method too, otherwise this will happen: >>> myobj[5] = 1. Traceback (most recent call last):
2 dni temu · Learn how Python represents data by objects and types, and how to use operators to manipulate them. The data model also covers mutability, garbage collection, containers, and the standard type hierarchy.
Modifying the behavior of an operator by redefining the method an operator invokes is called Operator Overloading. It allows operators to have extended behavior beyond their pre-defined behavior. Let us first discuss operators, operands, and their behavior before diving into the operator overloading.
20 gru 2009 · A class can implement certain operations that are invoked by special syntax (such as arithmetic operations or subscripting and slicing) by defining methods with special names. This is Python’s approach to operator overloading, allowing classes to define their own behavior with respect to language operators.
