python argparse模块通过后台传递参数

cmd.py
# -*- coding: utf-8 -*-
from PySide import QtGui, QtCore
import os,sys
import tory
import argparse
parser = argparse.ArgumentParser()
parser.add_argument("-v", "--verbosity", help="increase output verbosity")
parser.add_argument("-l", "--listdir", help="check root")
args = parser.parse_args()

if args.verbosity:
    app = QtGui.QApplication(sys.argv)
    trans = tory.Tuopan()
    trans.show()
    sys.exit(app.exec_())

if args.listdir:
    root=os.listdir(args.listdir)
    for f in root:
        print f
      
       
tory.py
#coding=utf-8
import sys
from PySide import QtGui
from PySide import QtCore
class Tuopan(QtGui.QWidget):
    def __init__(self):
        super(Tuopan, self).__init__()
        self.setWindowTitle("Tray!")
        self.resize(200,200)                
if __name__ == '__main__':
    app = QtGui.QApplication(sys.argv)
    trans = Tuopan()
    
    trans.show()
    sys.exit(app.exec_())

随后在cmd执行命令
python [​​​cmd.py​​​] -v 1 运行一个界面
python [​​​cmd.py​​​] -l d:/ 遍历d:/
即可。
