how to get a variable out of wxpython file open

Question

I am trying to get a variable out of wxPython file open dialog. I have 2 button which gets the path to 2 files with .GetPath() ?

this is the code I have so far

'def onclk1(event):
with  wx.FileDialog(panel, "OPEN EMG FILE", wildcard="TXT Files(*.txt)|*.txt",
                    style=wx.FD_OPEN | wx.FD_FILE_MUST_EXIST) as EmgFile:
    if EmgFile.ShowModal() == wx.ID_CANCEL:
        return "cancelled"
    emg = EmgFile.GetPath()

e1.Bind(wx.EVT_BUTTON, onclk1)

Now I need to pass the path outside def to another variable.

Thanks in advance

Just to provide another option, there is also a wx.FilePickerCtrl

import wx
import os

wildcard = "All files (*.*)|*.*"


class MainWindow(wx.Frame):

    def __init__(self):
        wx.Frame.__init__(self, None, title='File Selector')
        self.currentDirectory = os.getcwd()

        self.panel = wx.Panel(self)
        vbox = wx.BoxSizer(wx.VERTICAL)

        ie_box = wx.StaticBox(self.panel, -1, 'Please select the input file')
        ie_sizer = wx.StaticBoxSizer(ie_box, wx.VERTICAL)

        fl_box = wx.BoxSizer(wx.HORIZONTAL)
        self.fl_ctrl = wx.FilePickerCtrl(self.panel, message="Choose a file")
        fl_box.Add(self.fl_ctrl, 1, wx.ALL | wx.CENTER | wx.EXPAND, 5)
        ie_sizer.Add(fl_box, 1, wx.ALL | wx.CENTER | wx.EXPAND, 10)
        self.fl_ctrl.Bind(wx.EVT_FILEPICKER_CHANGED, self.on_open_file)

        vbox.Add(ie_sizer, 0, wx.ALL | wx.CENTER | wx.EXPAND, 5)
        self.panel.SetSizer(vbox)
        self.Center()
        self.panel.Fit()
        self.Show()

    def on_open_file(self, event):
        self.fl_ctrl.GetPath()


if __name__ == '__main__':
    app = wx.App()
    frame = MainWindow()
    app.MainLoop()
