Question

Which line of code will use the overloaded greater than comparison operation in Python? Answer where the big underscore is, next to the word `if`.

a) `if numA > numB:`
b) `if numA.__gt__(numB):`
c) `if numA.greater_than(numB):`
d) `if numA.compare(numB, '>'):`

Answer 1

The correct line of code is 'b) if numA.__gt__(numB):', which uses the dunder method __gt__ to perform an overloaded greater than comparison in Python.

Step-by-step explanation:

The correct line of code that will use the overloaded greater than comparison operation in Python is option a) if numA > numB:. In Python, the greater than comparison operator > can be used to compare two numbers directly, without the need for any special methods or functions.

The line of code that will use the overloaded greater than comparison operation in Python is:

b) if numA.__gt__(numB):

In Python, the double underscore methods, also known as "dunder" methods or magic methods, are used to override or implement behavior for built-in operations. The method __gt__ stands for "greater than" and is used to define the behavior of the greater than operator (>) for custom classes. When you use numA > numB, Python internally uses numA.__gt__(numB) if it has been specifically defined for the class of numA. The other options listed are not standard Python methods for comparison and, unless specifically defined in a custom class, would not be used for comparison operations.
