使用python删除mysql语句

Question

我是 MYSQL 新手，我面临着一个非常简单的 MYSQL 问题。我正在创建一个包含学生表的数据库，该表包含学生的姓名、ID（主键）。我需要根据用户选择的id（调用这个变量student_id）删除一条记录，那么如何使用python在mysql语句中编写这个？我已经尝试过，但我知道这是错误的 -->

cur.execute("Delete FROM students WHERE ID = student_id")

Answer 1

这应该适合你：

student_id = int(input('Please, enter an ID: '))  # In Python 3, you need to parse the user input for numbers.

statmt = "DELETE FROM `students` WHERE id = %s"
cur.execute(statmt, (student_id,))
conn.commit()  # You need to commit the transaction

Answer 2

@app.route('/delete', methods=['POST','GET'])
def delete():
if request.method == 'POST':
    flash("Data deleted Successfully")
    curobj = conn.cursor()
    id = int(input("enter the id:"))
    query = """DELETE FROM 'marks' WHERE id=%s"""
    curobj.execute(query,(id))
    conn.commit()
    

这段代码有什么错误？它不起作用。
