如何单击具有动态变量的类

class DynamicClass:
    def __init__(self, initial_variables):
        self.variables = initial_variables

    def add_variable(self, name, value):
        self.variables[name] = value

    def modify_variable(self, name, value):
        if name in self.variables:
            self.variables[name] = value
        else:
            print("Variable does not exist.")

    def delete_variable(self, name):
        if name in self.variables:
            del self.variables[name]
        else:
            print("Variable does not exist.")

    def get_variable(self, name):
        if name in self.variables:
            return self.variables[name]
        else:
            print("Variable does not exist.")

# 创建类的实例
dynamic_obj = DynamicClass({"variable1": 10, "variable2": "Hello"})

# 添加新的动态变量
dynamic_obj.add_variable("variable3", [1, 2, 3])

# 修改动态变量的值
dynamic_obj.modify_variable("variable1", 20)

# 删除动态变量
dynamic_obj.delete_variable("variable2")

# 获取动态变量的值
value = dynamic_obj.get_variable("variable3")
print(value)
