Python如何从Construct par访问容器函数中的嵌套值

Question

因此，我正在处理一个在Python中使用Construct模块的项目。我试图访问一个容器中的值，但是却抛出了一个错误

为了得到下面的语句，我使用了types[i].fieldlist

**Container Structure:**
 length = 90
 tpi_idx = 4407
 leaf_type = (enum) LF_FIELDLIST 4611
 substructs = ListContainer
    Container:
       leaf_type = (enum) LF_MEMBER 5389
       ....

到目前为止我已经试过了

`str(types[i].fieldlist.length)` = AttributeError: 'EnumIntegerString' object has no attribute 'length'

`str(types[i].fieldlist[0]) = Just returns 'T'

`str(types[i].fieldlist['length'] = Sting indices must be integers

代码如下所示：

for i in types:
        if types[i].leaf_type == "LF_FIELDLIST":
            types[i].substructs = ListContainer([resolve_typerefs(t, types, min) for t in types[i].substructs])
            # f.write(str(types[i].substructs))
        elif types[i].leaf_type == "LF_STRUCTURE":
            if types[i].name == "stack_st":

                types[i] = resolve_typerefs(types[i], types, min)
                #
                # items = types[i].items()
                # # for k, v in items:
                # #     print(str(k), str(v))
                f.write(str(types[i]))
                # print(types[i])
                print(str(types[i].fieldlist['length']))
        else:
            types[i] = resolve_typerefs(types[i], types, min)

到目前为止我已经试过了 str(types[i].fieldlist.length)=AttributeError:'EnumIntegerString'对象没有属性'length'

`str（types[i].fieldlist[0]）=仅返回'T'

`str（types[i].fieldlist['length']=Sting索引必须是整数
