Special functions in python are the functions which are used to perform special tasks. These special functions have__as prefix and suffix to their name as we see in__init__()method which is also a special function. Some special functions used for overloading the operators are shown below: ...
Similarly, we can overload other operators as well. The special function that we need to implement is tabulated below. Overloading Comparison Operators Python does not limit operator overloading to arithmetic operators. We can overload comparison operators as well. Here's an example of how we ...
Sinceintis a built-in type, its__mul__function knows nothing of outMatrixtype, so it returnsNotImplemented. You might think that Python would give an error at this point, but actually it tries one last thing: Python checks if the second argumentphas a__rmul__method. If not it gives an...
Python invokes __str__. So there is quite a lot happening behind the scenes. Changing the behavior of an operator so that it works with user-defined types is called operator overloading. For every operator in Python there is a corresponding special method, like __add__....
Welcome to your next lesson in Object-Oriented Programming in Python versus Java. In this lesson, we will take a look at operator overloading. You saw in your last lesson that Python provides a lot of built-in methods that objects inherit from…
