Python: What is the difference between a function and a method?

1# Function
2def greet(name):
3    return f"Hello, {name}"
4
5print(greet("Alice"))  # "Hello, Alice"
6
7# Method
8class Greeter:
9    def greet(self, name):  # self = instance
10        return f"Hello, {name}"
11
12g = Greeter()
13print(g.greet("Alice"))  # "Hello, Alice"
