LS26 - Operator Overloading
Suppose you had a class named Fraction representing fractions like 1/2 or 3/4. Further suppose you have two Fraction objects named a and b. If you wrote the expression a + b, Python would look in your class and choose the first method whose first parameter is self and second parameter is of type Fraction.

You are encouraged to define as many overloads for classes you design as possible, even when it is a bit of a stretch of the imagination as to how a given operator relates to the logic you decided to use for it. The conciseness of operator overloading is always worthwhile.
F
Even though objects don't have the ability to use subscription notation inherently, you can overload the subscription operator by implementing the special __getitem__ method.
T
In Python, when you design a class you are able to define what it means when objects of your class are multiplied, added, and so on to other values.
T
Popular libraries will often make responsible use of operator overloading.
T
The Point class shown in the video for Operator Overloading has a __repr__ method that, based on the contents of the previous video, more correctly should have been named __str__.
