Without really knowing whether there is such a module, I offer a
simple implementation of some of the functionality, which can easily
---- format.py ----
left = 0
center = 1
right = 2
space = width - len(line)
if alignment == center:
return ' '*(space/2) + line + \
' '*(space/2 + space%2)
elif alignment == right:
return ' '*space + line
return line + ' '*space
result = 
words = string.split(paragraph)
current, words = words, words[1:]
for word in words:
increment = 1 + len(word)
if len(current) + increment > width:
current = word
current = current+" "+word
What remains to be done, is the parsing of a format string (or
"picture") and - if you like, to add the handling of multiple
paragraph (separated by a double newline) and optionally "squeezing"
several empty lines into one etc. Parsing the format string might take
a bit of work, but the rest should be trivial.
