我想通过python简单地访问mysql的数据库。但是当我运行这段代码时：

import MySQLdb
db = MySQLdb.connect(host = "127.0.0.1",
                     port = "3306",
                      user="Bishnu",
                      passwd = "Pulchowk",
                      db = "student")
cursor =db.cursor()
cursor.execute("select * from basic_info")
numrows = int(cursor.rowcount)
for x in range(0,numrows):
    row = cursor.fetchall()
    print row[0],"-->",row[1]
db.cose()

它给出了一个错误：

Traceback (most recent call last):
  File "C:\Users\Bishnu\Desktop\database", line 6, in <module>
    db = "student")
  File "C:\Python27\lib\site-packages\MySQLdb\__init__.py", line 81, in Connect
    return Connection(*args, **kwargs)
  File "C:\Python27\lib\site-packages\MySQLdb\connections.py", line 187, in __init__
    super(Connection, self).__init__(*args, **kwargs2)
TypeError: an integer is required

那是什么 TypeError ：需要一个整数

为什么会出现这样的问题？要运行这段代码，我遇到了 3 个问题，但幸运的是这个论坛解决了我的两个问题，我想它也会解决吗？

db = MySQLdb.connect(host = "127.0.0.1",
                 port = "3306",
                  user="Bishnu",
                  passwd = "Pulchowk",
                  db = "student")

尝试更换：

port = "3306"

和

port = 3306

（去掉引号）
