Working with fixed format text db's

Many of the file formats I have to work with are so-called
fixed-format records, where every line in the file is a record,
and every field in a record takes up a specific amount of space.
For example, one of my older Python programs contains the
following to create a fixed-format text record for a batch of new
new = file("new.dat", "w")
if not new:
print "Error. Could not open file new.dat for writing."
raw_input("Press Return To Exit.")
for s in freshmen:
new.write(' '.ljust(10)) # Phone Number
new.write(' '.ljust(1254)) # Empty 'filler' space.
Luckily, the output format has not changed yet, so issues with
maintaining the above haven't arisen.
However, I'd like something better.
Is there already a good module for working with fixed format
records available? I couldn't find one.
If not, please suggest how I might improve the above code.
