如何在另一个函数中使用从wxPython按钮返回的值？

Question

I'm teaching myself Python/wxPython so apologies in advance for the newbie nature of my question and any incorrect terminology.

I've trawled the web and other suggested answers on here but I can't seem to find what I'm looking for.

I've got the following button that returns an open file (.txt) object:

def onHydroInputButton(self, event):
    dlg = wx.FileDialog(self, "Select file", self.dirname, "", "*.*", wx.OPEN)
    if dlg.ShowModal() == wx.ID_OK:
        input1 = open(dlg.GetPath())
        dlg.Destroy()
        return input1

I'd like to use input1 in another function. Could anybody show me how please?

for line in input1:

Obviously throws up an error that input1 is not defined.

Thanks in advance.

Calling the function returns some data. You need to store this, eg:

self.some_var = self.onHydroInputButton(event)

Now the output of the function is stored in self.some_var .
