align on char

[Mike C. Fletcher]

 >>> lines = (  'user1 : John Hunter',  'another user : Bill Bragg',  
'yet on more : Hi There', )
 >>> lines
('user1 : John Hunter', 'another user : Bill Bragg', 'yet on more : Hi 
There')
 >>> split = [ line.split( ':',1) for line in lines ]
 >>> split
[['user1 ', ' John Hunter'], ['another user ', ' Bill Bragg'], ['yet on 
more ', ' Hi There']]
 >>> maxLength = max([len(line[0]) for line in split ])
 >>> maxLength
13
 >>> aligned = [ '%s:%s'%(prefix.ljust(maxLength),suffix) for 
(prefix,suffix) in split ]
 >>> aligned
['user1        : John Hunter', 'another user : Bill Bragg', 'yet on 
more  : Hi There']
 >>> for line in aligned:
...     print line
...
user1        : John Hunter
another user : Bill Bragg
yet on more  : Hi There
