What is the difference between a function and a method in Python?a.Functions are defined using the def keyword, while methods are defined using the class keyworD.b.All of the abovec.Functions can be called without creating an instance of a class, while methods are called on instances of a class.d.Functions are used to perform specific tasks, while methods are used to operate on objects.

The difference between a function and a method in Python is as follows:

a. Functions are defined using the def keyword, while methods are defined within a class using the def keyword. This means that methods are associated with objects/classes, while functions are not.

b. This option is not valid as there are no other options above to consider.

c. Functions can be called independently, without creating an instance of a class. On the other hand, methods are called on instances of a class, meaning you need to create an object of the class before you can call a method.

d. Both functions and methods are used to perform specific tasks. The main difference is that methods are designed to operate on the data (attributes) within their class or the object instance, while functions operate on the arguments passed to them.
