使用wxpython将终端输出传递给GUI

Question

Hi all i am using python 2.7 and for GUI wxpython, in linux environment. I wants to redirect output from terminal to Message box, how it will happen? My code is:

 p = subprocess.call(" grep "Wanted" .filename | awk '{print $2}' | cut -c11-20", shell=True)

This will give proper output in terminal,but when i call it in message box it shows "0".

 wx.MessageBox(" file name:'%s' % (str(p)), "info")

how to print those which are displayed in terminal , i am newbie to python world and have less knowledge in python. Searched for answer but couldn't any answer.so dropping here for solution and guidance. Thanks in advance

Might be prefered/simpler to use Popen (But I rarly use subprocess.call so I do no know). But you example should work fine (with the mentioned fix from Ashwini Chaudhary), from what I see.

import subprocess
import wx

def main():
    p = subprocess.Popen(['ls', '-a'], stdout = subprocess.PIPE)
    text = p.stdout.readlines()
    text = "".join(text)

    wx.MessageBox("file names:\n%s" % text, "info")

if __name__ == '__main__':
    app = wx.PySimpleApp()
    main()

Anyways: Any reason to involve Bash, cant python do the same?
