Not that it would solve your problems, but you can write the above much more elegantly using a dictionary:
# normalize the token
try:
out += {
'house' : 'hse',
'ground' : 'grd',
'gnd' : 'grd',
'front' : 'fnt',
'floor' : 'flr',
...
}[tok]
except KeyError:
out += tok
# add a field delimiter if the token isn't among the exceptions for those
if tok not in ('borough', 'city', 'of', 'the', 'at', 'incl', 'inc'):
out += ADDR_FIELD_DELIM
You should probably define those lists outside the for-loop though, I'm not sure the Python interpreter is smart enough to declare those lists only once otherwise. The concept remains though.
