請指導我我是新的python。我在添加庫管理器部分創建圖書館管理項目，我插入所有必需的信息，但無法將數據存儲在數據庫中。 按我的想法我不能夠讀取數據從下面的標籤是我在存儲的數據庫，我在標籤申請正在插入數據面臨問題的代碼無法從文本標籤讀取數據並將其存儲在數據庫中

請編輯您的帖子糾正語法。在Python中，縮進非常重要，目前它是一團糟;-) - 粘貼代碼，突出顯示它並使用Ctrl + K鍵縮進整個塊。 – Maurice
你甚至沒有試圖從標籤讀取數據。 –
感謝您的輸入在Addlib類中，我通過使用get方法讀取數據，但是我認爲如果可能的話，我在數據庫中存儲數據時會出現一些錯誤，請您提出建議，以便它可以工作 – Tathe
