python學習總結之外部傳參

想要從程序外面將參數傳人程序內部的做法：

利用sys這個模塊來進行操作，

#!/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' 結果顯示：sys.argv這個參數就好比我們java中的額main函數中經常看到的argv[]

[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']
