想要从程序外面将参数传人程序内部的做法:
利用sys这个模块来进行操作,
#!/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'
结果显示:sys.argv这个参数就好比我们java中的额main函数中经常看到的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']
