将类类型的字典作为参数，将其实例的字典作为返回类型

class MyClass:
    def __init__(self, param1, param2):
        self.param1 = param1
        self.param2 = param2
    
    def my_method(self):
        # Some code here
        pass

def create_instance(class_dict):
    instance_dict = {}
    for class_name, class_params in class_dict.items():
        # Create an instance of the class with the given parameters
        instance = globals()[class_name](**class_params)
        # Convert the instance to a dictionary
        instance_dict[class_name] = instance.__dict__
    return instance_dict

# 定义类类型的字典
class_dict = {
    'MyClass': {'param1': 'value1', 'param2': 'value2'}
}

# 调用函数创建实例的字典
instance_dict = create_instance(class_dict)

# 打印实例的字典
print(instance_dict)

{'MyClass': {'param1': 'value1', 'param2': 'value2'}}
