Question

我当前正在创建一个MySQL数据库，该数据库想使用for循环遍历包含表中值的数据字段。我已经成功完成了代码，但是当我想运行脚本以最终写入数据库时，会出现

错误

python3 blueteamcolorassignment9.py
/usr/bin/python3: can't find '__main__' module in 'blueteamcolorassignment9.py'

假设要从此for循环中接收值。

python3

>>> cursor = conn.cursor()
>>> query = ('SELECT empid,lastname,firstname,salary FROM employees')
>>> cursor.execute(query)
>>> for (empid,lastname,firstname,salary) in cursor:
...  print(empid,lastname,firstname,salary)
... cursor.close()
  File "<stdin>", line 3
    cursor.close()
         ^

>>> cursor.close()

Use exit() or Ctrl-D (i.e. EOF) to exit

创建文件并想要创建数据库后出现主模块错误
