我尝试通过Python访问MySQL数据库中的数据,然后我尝试了以下方法:
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()
然后它会显示错误。
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
然后我还尝试了删除密码
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):

可能的解决方案是什么?
