国外牛人说要多学习不同的编程语言，感受它们的不同艺术，学习其长短，有利于开拓思维。所以除了JAVA，一直想找另外一门比较轻便的语言来学习，例如，Python！好，让我们坐上 google 旅游大巴，去享受Python吧！

Vamei写的傻瓜基础教程：

学一门语言希望知道为啥它值得学习？与你现在所掌握的有何不同。下面的文章挺好的：

中国人很多太浮躁。做技术的我希望不要浮躁。Python很简单，但是似乎底层的实现都屏蔽了，作为一名程序员，我还是推荐用JAVA作为职业生涯的学习语言。当然如果你会C那就更好了。

好了，下面介绍下如何在windows下面使用Python：

下载安装：

https://www.python.org/ftp/python/2.7.6/python-2.7.6.msi

安装后都不用设置什么PATH之类的，如何开始编程请看下面：

windows下安装cx_Oracle:

1. 百度搜索适用版本的简易 oracle client ，例如 instantclient-basic-win32-11.2.0.1.0.zip； csdn有资源

2. 解压到某路径，将此路径加入 PATH

3. 百度搜索使用版本的 cx_Oracle , 例如 cx_Oracle-5.1.2-10g.win32-py2.7.msi，安装

4. 验证：

>>> import cx_Oracle>>> conn = cx_Oracle.connect("usr/pwd@123.13.23.4:1800/test")>>> cursor = conn.cursor()>>> cursor.execute("select 1 from dual")<__builtin__.OracleCursor on <cx_Oracle.Connection to usr@123.13.23.4:1800/test>>>>> row = cursor.fetchone()>>> print row[0]1>>> cursor.execute("select * from 888")Traceback (most recent call last):  File "<pyshell#7>", line 1, in <module>    cursor.execute("select * from 888")DatabaseError: ORA-00903: ????>>> cursor.execute("select * from sales_orders where rownum = 1")<__builtin__.OracleCursor on <cx_Oracle.Connection to usr@123.13.23.4:1800/test>>>>> rows = cursor.fetchall()>>> for row in rows:print row(214237, 100037, 'LS2012090300494abc', '20828031Q6H71', 'DELIVER_ALL', 'FINANCE_AUDIT_YES', 'PRE_DISTRIBUTION_YES', 'DISPATCH_ALL', 'INVOICE_ALL', 'NONE', datetime.datetime(2012, 8, 28, 23, 20, 1), '1', 1, 105287, 124743, 117012, '???', '???', '???', None, '13302607047', None, None, 102878, '???????C175?', '523686', datetime.datetime(2012, 8, 29, 22, 45, 5), None, 1099, 0, '1', 1099, '???', None, None, '???', 102878, '???????C175?', '13302607047', None, None, 'A', '1', None, 'D', None, None, None, 105317, '?????', datetime.datetime(2012, 9, 3, 9, 23, 49), '??', datetime.datetime(2012, 9, 3, 11, 41, 52), 'false', 'false', 'false', 0, None, None, 'SHIPPED_ALL', 'SHIPPED_ALL_OVER', 'PAYED', 'VERIFICATION_ALL', 'NONE', None, 'NONE', 'D', 'D', None, None, None, None, 'ORDER_TRUNED_TO_DO', 0, None, '1', None, None, None, None, None, None, 'DIRECT', None, None, None, None, None, None, None, None, None, None, 118697, None, None, None, None, None, None, None, None, None, None, None, 0, 1, None, None)>>> print rows[0][0]214237>>> print rows[0][2]LS2012090300494abc>>> print cursor.rowcount;1>>> cursor.close()>>> conn.close()
