初试python

CODE:

#!/bin/env python

import sys, os, time;
from datetime import date;


# 1. set dest file.
prefix = 'mms://211.89.225.102/cnr/channel2/yyzy';
postfix = '210000.wma';
today = date.fromtimestamp( time.time() );
yesterday = today.fromordinal( today.toordinal() - 1 );

target_name = prefix + yesterday.strftime('%Y%m%d') + postfix;
print 'target_name = ', target_name;

# 2. download use flashget
path = 'C:\\Program Files\\fget\\';
bin = 'flashget.exe';

dest_store = 'G:\\';

cmd = path + bin;
arg1 = " " + target_name;
arg2 = " " + dest_store;

print 'cmd = ', cmd, 'arg1 = ', arg1, 'arg2 = ', arg2;

os.execlp( cmd, arg1, arg2);

flashget原来还可以通过命令行来用呢。
python有自己的urllib/urlib2，很好用的，可以试试。

楼主的程序一个indent都没有用到，咋一看还看不出是python来，哈哈。
