This is exactly the logic I use,... Eliminating all unrelated stuff, I
have something like (thanks for the imp hint):
def wxGUI():
import wx
wx...
def tkGUI():
import Tkinter as tk
tk....
def cml():
command line
def GUI():
if options['cml']:
cml()
else:
if imp.find_module('wx'):
wxGUI()
elif imp.find_module('Tkinter'):
tkGUI()
else:
cml()
After a user loads this module (without wx loaded automatically as
before), he can call cml() or GUI().
