これは、生徒の記録を追加、削除、編集、および表示する単純な python プログラムです。問題は、DELETE と EDIT が機能しないことです。理由はわかりませんが、「？」を削除しようとしたとき。DELETE ダンクションで、列が 8 つしかなく、10 列が必要であるというエラーが発生しました。しかし、もともとは 9 列しかありません。10にするために他のものをどこで手に入れたのかわかりません。助けてください.. :(

116 行目と 117 行目でemail、テーブルに挿入しようとしたときに 2 回リストしました。

student=(studentnum,name,age,email,birthday,address,email,course,year,section)
cur.execute("INSERT INTO student(studentnum,name,age,email,birthday,address,email,course,year,section) VALUES(?,?,?,?,?,?,?,?,?)",student)

次のようにする必要があります。

student=(studentnum,name,age,birthday,address,email,course,year,section)
cur.execute("INSERT INTO student(studentnum,name,age,birthday,address,email,course,year,section) VALUES(?,?,?,?,?,?,?,?,?)",student)

ちなみに、 PEP8を調べても害はないかもしれませんが、デバッグに役立つ可能性があります。

deleteまた、あなたの機能も適切に機能している とは思いません。

注:tracebackいつかまた問題が発生する場合は、発生しているエラーを投稿してください。

INSERT INTO student(studentnum,name,age,email,birthday,address,email,course,year,section)
                                          ^                      ^

emailが繰り返されます。

注: DELETE ステートメントでもパラメーターを使用する必要があります。

cur.execute("DELETE FROM student WHERE name = ?", (studentnum1))
