python - Flask mysql 查询 = 查询% self._escape_args(args, conn) TypeError : not all arguments converted during string formatting

Question

我几乎尝试了所有方法来使我的第一个 Flask 任务在 cloud9 上运行，但仍然给我这个错误

cursor.execute('''INSERT INTO studentmaster 
                       (Student_Id,Student_FirstName,Student_LastName,
                        Course_Id,Gender,Residential_Address,
                        PhoneNo,Email,Password) 
                  VALUES (%s,%s,%s,%s,%s,%s,%s)''',
               (stid,firstname, lastname, coursename, gender, address,
                phone, email,password))

Answer 1

表名中有 9 列，值中有 9 个变量，但值中只有 7 %s (%s......%s)

cursor.execute('INSERT INTO studentmaster 
  (Student_Id,Student_FirstName,Student_LastName,Course_Id,Gender,Residential_Address,PhoneNo,Email,Password) 
  VALUES (%s,%s,%s,%s,%s,%s,%s)',
  (stid,firstname, lastname, coursename, gender, address,phone, email,password))
