python学习第一天

[hfsross]

首先说明，我写过几年的程序，今天突然想学python。
觉得不错，今天第一天学习
习惯搜索引擎，然后代码
还是经常出错提示，
所以跑来这里提问一下，希望大伙可以给我帮忙

我想写一个数据库连接
我已经装了MySQL-python-1.2.2.win32-py2.6.exe（没有重启，不知是否需要重启）
以下代码

# coding=utf-8
from MySQLdb import *
def conn():
    cn=Connection('127.0.0.1','root','','test')

cur=cn.cursor()
cur.execute('select * from test')

row=cur.fetchone()

print row[0]
print row[1]

if __name__=='__main__':
    conn()

以下报错
Traceback (most recent call last):
File "D:\py\test.py", line 2, in <module>
from MySQLdb import *
File "C:\Python26\Lib\site-packages\MySQLdb\__init__.py", line 34, in <module>
from sets import ImmutableSet
File "C:\Python26\lib\sets.py", line 85, in <module>
stacklevel=2)
File "C:\Python26\lib\warnings.py", line 29, in _show_warning
file.write(formatwarning(message, category, filename, lineno, line))
TypeError: idle_formatwarning_subproc() takes exactly 4 arguments (5 given)

不import *试试。

import MySQLdb
def conn():
    cn = MySQLdb.Connection('127.0.0.1','root','','test')

Traceback (most recent call last):
File "D:\py\test.py", line 2, in <module>
import MySQLdb
File "C:\Python26\Lib\site-packages\MySQLdb\__init__.py", line 34, in <module>

File "C:\Python26\lib\sets.py", line 85, in <module>
stacklevel=2)
File "C:\Python26\lib\warnings.py", line 29, in _show_warning
file.write(formatwarning(message, category, filename, lineno, line))
TypeError: idle_formatwarning_subproc() takes exactly 4 arguments (5 given)

也是一样报错

你用的是IDLE吧？直接用python命令运行试试。

[hfsross]

是啊，我用的是idle，我用命令行也报这样的错
Traceback (most recent call last):
File "<pyshell#0>", line 2, in <module>
from MySQLdb import *
File "C:\Python26\Lib\site-packages\MySQLdb\__init__.py", line 34, in <module>
from sets import ImmutableSet
File "C:\Python26\lib\sets.py", line 85, in <module>
stacklevel=2)
File "C:\Python26\lib\warnings.py", line 29, in _show_warning
file.write(formatwarning(message, category, filename, lineno, line))
TypeError: idle_formatwarning_subproc() takes exactly 4 arguments (5 given)

用命令行怎么会有pyshell#0这样的东西啊？
你应该把代码保存到文件中，比如叫test-mysql.py，然后运行python test-mysql.py。

[hfsross]

果然好了，为什么呢？

[king_2007]
