Stripping whitespace

I am taking a database class so I'm not asking for specific answers.
Well I have this text tile:
http://www.cs.tufts.edu/comp/115/projects/proj0/customer.txt
And this code:
# Table and row classes used for queries
class Row(object):
def __init__(self, column_list, row_vals):
print len(column_list)
print len(row_vals)
for column, value in column_list, row_vals:
if column and value:
setattr(self, column.lower(), value)
class Table(object):
def __init__(self, table_name, table_fd):
self.name = table_name
self.table_fd = table_fd
self.rows = []
self._load_table()
def _load_table(self):
counter = 0
for line in self.table_fd:
# Skip the second line
if not '-----' in line:
if counter == 0:
# This line contains the columns, parse it
column_list = line.split()
else:
# This is a row, parse it
row_vals = line.split()
# Create a new Row object and add it to the
table's
# row list
self.rows.append(Row(column_list, row_vals))
counter += 1
Because the addresses contain spaces, this won't work because there
are too many values being unpacked in row's __init__'s for loop. Any
suggestions for a better way to parse this file? I don't want to cheat
but just some general ideas would be nice. Thanks!
