TypeError: getattr(): attribute name must be string

Question

我需要将输出组织为电报机器人中的按钮。例如，我创建了一个字典，我需要从中推断键和对象，将其形成为字符串并将其放置在将通过 for 循环的按钮中。但是我看到的不是正确的结果，而是这个错误：TypeError: getattr(): attribute name must be string。这是我的代码：

def choose_language(update, conext):
    chat = update.effective_chat
    land = {
        'Eng':'en',
        'Rus':'ru'
    }
    b = []
    for k,v in land.items():
        a = k, v
        b.append(a)
    flatten = [str(item) for sub in b for item in sub]
    for key in flatten:
        button = [InlineKeyboardButton(f"{key}", callback_data='{key}')]

    #for key in land:
        #button = InlineKeyboardButton(str(land[key]).capitalize(), callback_data=str(key))
    reply_markup = InlineKeyboardMarkup(button)
    update.message.reply_text('Choose target language:', reply_markup=reply_markup)

Answer 1

InlineKeyboardMarkup 的参数必须是列表的列表 - 您传递的是一个简单的列表。

Answer 2

所以我做到了。问题是当它引发 AttributeError: the list object has no to_dict attribute 时，我将按钮制作为列表。然后我放弃了 dict.attributes 并决定缩短 flatten 以仅获取字符串对象。

d = {
    'Eng':'en',
    'Rus':'ru',
    'Ger':'ge'
}
    button_demo = []
    b = []
    bb = []
    for k, v in d.items():
        a = k
        b.append(a)
        s = v
        bb.append(s)
    flatten = [str(sub) for sub in b]
    flatten1 = [str(sub) for sub in bb]
    for ix in range(len(flatten)):
        button = [InlineKeyboardButton(f"{flatten[ix]}", callback_data=f'{flatten1[ix]}')]
        button_demo.append(button)
reply_markup = InlineKeyboardMarkup(button_demo)
update.message.reply_text('Choose target language:', reply_markup=reply_markup)
