Adjusting Text: ljust(), rjust(), center(), zfill(), expandtabs()

The functions for adjusting text are as handy and convenient as the parsing functions. You'll use them a lot, particularly for attractive report printing.

The ljust(s, width) function left-justifies a string to a given width. The rjust(s, width) function right-justifies it. The center(s, width) function centers a string to a given width. Here are examples of all three:

>>> rjust("String",20)
'              String'

>>> rjust ("str",20)
'                 str'

>>> ljust("String",20)
'String              '

>>> ljust("str",20)
'str                 '

>>> center("str",20)
'        str         '

>>> center("String",20)
'       String       '

zfill(snum,width) pads a numeric string with leading zeros.

>>> zfill("0.1", 10)
'00000000.1'

expandtabs(s,tabsize) converts ...
