Dave is correct, but if you want to format text to a certain width, it is 
better to have Python count how many spaces you need:


py> 'spam'.rjust(20)
'                spam'
py> 'spam'.ljust(20)
'spam                '
py> 'spam'.center(20)
'        spam        '


In recent versions, you can even specify the fill character:

py> 'spam'.center(20, '.')
'........spam........'
