我尝试通过python访问mysql数据库中的数据然后我尝试了

import MySQLdb

db = MySQLdb.connect(host = "127.0.0.1",
                     port = 3306,
                      user="Bishnu",
                      password = "Pulchowk",
                      db = "telecom_db")
cursor =db.cursor()
cursor.execute("select * from profile")
numrows = int(cursor.rowcount)
for x in range(numrows):
    row = cursor.fetchone()
    #if (row):
    print row[0], row[1]

cursor.close()

db.cose()

然后它显示错误

Traceback (most recent call last):
  File "D:\Bishnu\BE\4th year\7th semester\Major Project I\Workspace\Bishnuji\default\first.py", line 43, in <module>
    db = "telecom_db")
  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: 'password' is an invalid keyword argument for this function

然后我也尝试删除密码

import MySQLdb

db = MySQLdb.connect(host = "127.0.0.1",
                     port = 3306,
                      user="Bishnu",
                      #password = "Pulchowk",
                      db = "telecom_db")
cursor =db.cursor()
cursor.execute("select * from profile")
numrows = int(cursor.rowcount)
for x in range(numrows):
    row = cursor.fetchone()
    #if (row):
    print row[0], row[1]

cursor.close()

db.cose()

仍然显示错误

Traceback (most recent call last):
  File "D:\Bishnu\BE\4th year\7th semester\Major Project I\Workspace\Bishnuji\default\first.py", line 43, in <module>
    db = "telecom_db")

  File "C:\Python27\lib\site-packages\MySQLdb\connections.py", line 187, in __init__
    super(Connection, self).__init__(*args, **kwargs2)
_mysql_exceptions.OperationalError: (1044, "Access denied for user ''@'localhost' to database 'telecom_db'")

可能是什么解决方案？

从文档看来，参数的正确命名是passwd

检查您是否在数据库上设置了密码。通常用户名和密码不会更改，默认用户名 = 'root'，密码填充为空，即密码 = ''。如果您设置了密码并忘记了密码，那么您可以按照如何找回我的 MySQL 用户名和密码？
