def OpenFile():
    name = askopenfilename(initialdir="C:/Users/Batman/Documents/Programming/tkinter/",
                           filetypes =(("Text File", "*.txt"),("All Files","*.*")),
                           title = "Choose a file."

    #Using try in case user types in unknown file or closes without choosing a file.
    try:
        with open(name,'r') as UseFile:
            print(UseFile.read())
    except:
