	You can use the string methods ljust, rjust and zfill:

 >>> "xxx".rjust(10)
'       xxx'
 >>> "xxx".ljust(10)
'xxx       '
 >>> "xxx".zfill(10)
'0000000xxx'

	Note that the string will not be truncated if it's more than (here) 10 
characters long, but you can use slicing to get around that:

 >>> "xxxxxxxxxxxxxxxx".rjust(10)[:10]
'xxxxxxxxxx'
