On the other hand, I don't see how this is superior to an exception-based
approach...
def GUI():
if options["cml"]:
cml()
else:
for ui in wxGUI, tkGUI, cml:
try:
ui()
except ImportError:
pass
else:
break
...especially as you have to deal with ImportError exceptions, too:
>>> import imp
>>> imp.find_module("not_there")
Traceback (most recent call last):
File "<stdin>", line 1, in ?
ImportError: No module named not_there
