学习python的第十三天之函数——函数的返回值

return的用法

返回单个值

def add(a, b):
    return a + b

result = add(3, 5)
print(result)  # 输出: 8

返回多个值

def get_coordinates():
    return (10.0, 20.0)

x, y = get_coordinates()
print(x, y)  # 输出: 10.0 20.0

def get_coordinates_direct():
    return 10.0, 20.0

x, y = get_coordinates_direct()
print(x, y)  # 输出: 10.0 20.0

返回布尔值

def is_even(number):
    return number % 2 == 0

print(is_even(4))  # 输出: True
print(is_even(5))  # 输出: False

返回None

def do_nothing():
    pass  # 或者没有return语句

result = do_nothing()
print(result)  # 输出: None

返回函数

def outer_function():
    def inner_function():
        return "Hello from the inner function!"
    return inner_function

inner_func = outer_function()
print(inner_func())  # 输出: Hello from the inner function!

返回对象

class MyClass:
    def __init__(self, value):
        self.value = value

def create_myclass_instance(value):
    return MyClass(value)

obj = create_myclass_instance(10)
print(obj.value)  # 输出: 10
