What are some examples of functions and methods in Python?

In Python, a function is defined using the 'def' keyword. For example, 'def add(a, b): return a + b' is a simple function that adds two numbers.

Can you explain the difference between a function and a method?

Sure! A function is a standalone block of code, while a method is a function that is associated with an object. For example, 'list.append()' is a method that adds an item to a list.

Can you give me an example of a built-in method?

Absolutely! The 'str.upper()' method converts a string to uppercase. For instance, '"hello".upper()' will return 'HELLO'.

What about lambda functions?

Lambda functions are small anonymous functions defined with the 'lambda' keyword. For example, 'lambda x: x * 2' creates a function that doubles its input.
