What is the pythonic way to do this ?
I like list comps...
>>> jj = '1234567890123456789'
>>> ",".join([jj[ii:ii+3] for ii in range(0,len(jj),3)])
'123,456,789,012,345,678,9'
>>>

Less beautiful but more correct:
>>> ",".join([jj[max(ii-3,0):ii] for ii in
range(len(jj)%3,len(jj)+3,3)])
'1,234,567,890,123,456,789'

Is it?
jj = '234567890123456789'
",".join([jj[max(ii-3,0):ii] for ii in range(len(jj)%3,len(jj)+3,3)])
',234,567,890,123,456,789'
Schluck!
Even more ugly:
",".join([jj[max(ii-3,0):ii] for ii in
range(len(jj)%3,len(jj)+3,3)]).strip(",")
'234,567,890,123,456,789'

At least one other solution in this thread had the same problem.
