I'm not sure it's very elegant, but what about
if tn.__name__ in ['list','tuple','time.struct_time']
I actually prefer
try:
from time import struct_time
except ImportError:
_TimeTypes = (ListType, TupleType)
else:
_TimeTypes = (ListType, TupleType, struct_time)
if tn in _TimeTypes

For that, I'd just write
try:
self.normalDate = int("%04d%02d%02d" % normalDate[:3])
except TypeError:
# else code
