What is the method for defining functions in Python?

In Python, there are several methods for defining functions.

1. function

def my_function():
    # 函数体代码
    pass

1. You can add parameters to a function to accept input values. Parameters can be required, default, or variable. For example:

def greeting(name):
    print("Hello, " + name)

def add_numbers(x, y=0):
    return x + y

def sum_numbers(*numbers):
    total = 0
    for number in numbers:
        total += number
    return total

1. come back

def multiply(x, y):
    return x * y

1. lambda is a term often used in mathematics and computer programming to refer to a parameter or variable.

multiply = lambda x, y: x * y

The above are common methods used for defining functions, and you can choose the suitable one based on your specific needs.
