MRAB's solution was deserving of a more complete solution:
>>> def parse_address(address):
# Handles poorly-formatted addresses:
# 100 RAMPART S ST -- direction in wrong position
# 45 JOHN CHURCHILL CHASE ST -- two spaces before type
#addresslist = ['num', 'dir', 'name', 'type']
addresslist = ['', '', '', '']
parts = address.split()
if parts[-2] in ('E', 'W', 'N', 'S'):
addresslist[1] = parts[-2]
addresslist[2] = ' '.join(parts[1 : -2])
else:
addresslist[2] = ' '.join(parts[1 : -1])
addresslist[0] = parts[0]
addresslist[3] = parts[-1]
return addresslist
>>> parse_address('45 John Churchill Chase N St')
['45', 'N', 'John Churchill Chase', 'St']
>>> parse_address('45 John Churchill Chase St')
['45', '', 'John Churchill Chase', 'St']
