How can I add a file extension using TKinter?

I am trying to save a pickle dump to a .pkl file using Tkinter. I followed the documentation but when I save the file it has no extension. This is a snippet:

root = tk.Tk()
messagebox.showinfo("Select Save Location", "Please save the Feature list")
savedf = filedialog.asksaveasfilename(filetypes=[("Pickle Dumps","*.pkl")])

How do I make it so that if I name the file hello it will save as hello.pkl when the user only specifies the file name?
