I think you are talking about padding strings with spaces   One way to do this is with string format codes   For example  if you want to pad a string to a certain length with spaces  use something like this   String padded   String format   -20s   str     In a formatter    introduces a format sequence  The - means that the string will be left-justified  spaces will be added on the right of the string   The 20 means the resulting string will be 20 characters long  The s is the character string format code  and ends the format sequence
