Python 入门 hello world ＆ 在ubuntu下安装MySQLdb

新建一个文件

 

#!/usr/bin/env python
#filename hello.py
print 'Hello World'

 

chmod +x hello.py

 

python hello.py 

 

就可以看到输出Hello World 了

 

Ubuntu 下安装MySQLdb

1.首先 sudo apt-cache search python-mysqldb

2.安装完毕后 

 

~$ python
Python 2.6.2 (release26-maint, Apr 19 2009, 01:56:41) 
[GCC 4.3.3] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import MySQLdb
/var/lib/python-support/python2.6/MySQLdb/__init__.py:34: DeprecationWarning: the sets module is deprecated
  from sets import ImmutableSet
>>> MySQLdb.version_info
(1, 2, 2, 'final', 0)

 会看到一个warnings ，可以忽略，因为是shell影响了
