[FIXED] Spyder 3.7 - How to store value in a variable from a function

Issue

I realize this is probably really simple, I do it in Matlab all the time. Right now, all I want to do is use a button in tkinter to open a file dialog, choose a file, and store the pathname in a variable.

class Functions:
    def FileDialog(Pathname):
        Pathname = tkFileDialog.askopenfilename()

Funks = Functions()
Btn1 = tkinter.Button(MainWindow, text = "Browse", command = Funks.FileDialog)

After the function is done, where does "Pathname" go? How can I view it in the variables explorer?

Update: I've structured the code differently now and here it is in its entirety

##########################################
import tkinter as tk                     #
from tkinter import Frame                #
import tkinter.filedialog as tkFileDialog#
##########################################

class Window(Frame):
    def __init__(self, master = None):
        Frame.__init__(self, master)
        self.master = master
        self.MainWindow()

    def MainWindow(self):
        self.master.title("The SHIFT Show"); self.pack() 
        Btn1 = tk.Button(self, text = "Browse", command = self.FileDialog)
        Btn1.place(x = 0, y = 0); Btn1.pack()
        Btn2 = tk.Button(self, text = "Close Window", command = self.Exit) 
        Btn2.place(x = 0, y = 0); Btn2.pack()
        Btn3 = tk.Button(self, text = "Pathname?", command = self.PathTest)
        Btn3.place(x = 0, y = 0); Btn3.pack()

    def FileDialog(self):
        Pathname = tkFileDialog.askopenfilename()
        return Pathname

    def Exit(self):
        exit() #DOESNT WORK

    def PathTest(self,Pathname):
        print(Pathname)

root = tk.Tk()
app = Window(root)
root.geometry("500x500+2500+1100")
root.mainloop()

Solution

I got it to do what I wanted. yay.

        self.MainWindow()

    def MainWindow(self):
        self.master.title("The SHIFT Show"); self.pack() 
        # BUTTONS
        ## File dialog button
        Btn1 = tk.Button(self, text = "Browse", command = self.FileDialog)
        Btn1.place(x = 0, y = 0); Btn1.pack()
        ## Close window button
        Btn2 = tk.Button(self, text = "Close Window", command = self.Exit) 
        Btn2.place(x = 0, y = 0); Btn2.pack()
        ## Test button for....things
        Btn3 = tk.Button(self, text = "Pathname?", command = self.PathTest)
        Btn3.place(x = 0, y = 0); Btn3.pack()

    def FileDialog(self):
        global Pathname
        folderpath = tkFileDialog.askdirectory()
        Pathname = folderpath        

    def Exit(self):
        exit() # STILL DOESNT WORK

    def PathTest(self):
        print(Pathname) # Outputs the folder path to the console (so I know it's there)

root = tk.Tk()
app = Window(root)
root.geometry("500x500+2500+1100")
root.mainloop()
