csvの行ごとにデータを保存する方法は？

Question

最近、私はログインシステムを設計するプロジェクトを持っています。私が使用しなければならないコンテナはcsvです。私の問題は、ユーザーが新しいアカウントにサインアップするときに、行ごとにユーザー情報を保存できないことです。新しいユーザーが新しいアカウントにサインアップすると、古いアカウントの情報がカバーされ、削除されます。

はここでそれは私が最近、データを保存する方法で、クラスNew_Toplevel_2で私のコード→

誰でも私にこの問題の解決を手伝ってもらえますか？

Answer 1

はわからないが、私はあなたが行を変更すべきだと思う：

f = open('example.csv', 'w') 

f = open('example.csv', 'a') 

に wは、たびに、既存のデータは削除されますので、開いているファイルを切り捨てます。 aは、ファイルの末尾に改行を追加して挿入することを意味します。
