list comprehension:
http://docs.python.org/tutorial/datastructures.html#list-comprehensions

string formatting:
http://docs.python.org/library/stdtypes.html#string-formatting-operations

here's some common examples:

# strings
 >>> f = 'foo'
 >>> '%8s' % f
'     foo'
 >>> '%-8s' % f
'foo     '

# ints
 >>> '%04d' % 10
'0010'
 >>> '% 04d' % 10
' 010'
 >>> '% 04d' % -10
'-010'

#floats
 >>> '%.3f' % 1.123456
'1.123'
 >>>
