本文介绍了一个简单的Python脚本，该脚本演示了如何使用sys模块来打印命令行参数及PYTHONPATH环境变量。通过这个示例，读者可以了解如何在Python程序中获取运行时的路径信息及传入的参数。

#!/usr/bin/python
#filename:using_sys.py
import sys
print 'the command line arguments are:'
for i in sys.argv:
print i
print '\n\n The PYTHONPATH is\n',sys.path,'\n'

[root@fsailing1 python]# python using_sys.py we are studying python
the command line arguments are:
using_sys.py
we
are
studying
python

The PYTHONPATH is
['/root/python', '/usr/lib/python24.zip', '/usr/lib/python2.4', '/usr/lib/python2.4/plat-linux2', '/usr/lib/python2.4/lib-tk', '/usr/lib/python2.4/lib-dynload', '/usr/lib/python2.4/site-packages', '/usr/lib/python2.4/site-packages/Numeric', '/usr/lib/python2.4/site-packages/gtk-2.0']
