我想从一个lambda返回两个值并赋值给另一个，但我得到了错误

def lambda_function():
    # 执行一些操作
    return value1, value2

result = lambda_function()
var1, var2 = result

def lambda_function():
    # 执行一些操作
    return {'key1': value1, 'key2': value2}

result = lambda_function()
var1 = result['key1']
var2 = result['key2']

class MyObject:
    def __init__(self, value1, value2):
        self.value1 = value1
        self.value2 = value2

def lambda_function():
    # 执行一些操作
    return MyObject(value1, value2)

result = lambda_function()
var1 = result.value1
var2 = result.value2
