Calling a wxpython GUI class from another class

First create a python file and save it e.g noname.py and have your wx code in it:

import wx

class MyFrame(wx.Frame):
    def __init__(self, parent , id, title):
        wx.Frame.__init__(self, parent , id, title)
        self.panel = wx.Panel(self,-1)
        

create another python file and have the following code in it, save it as testing .py

import wx
from noname import MyFrame

app = wx.App()
f = MyFrame(None, -1, "MAIN FRAME")
f.Show()

app.MainLoop()

Now anytime at all you run the file testing.py, the GUI should be created.
