I guess my slicing was wrong, l[-1] worked Regards, Philippe -- http://mail.python.org/mailman/listinfo/python-list

adding a character to the last string element of a list

Hi, I have the following question: l = ['ABCDE','FGHI'] l[1:] #returns ['FGHI'] l[1:][0] #return 'FGHI' a = l[1:][0] + 'J' #a becomes 'FGHIJ' l[1:][0] += 'J' #NO ERROR BUT l[1:][0] == 'FGHI' What am I missing ? Thanks, Philippe -- http://mail.python.org/mailman/listinfo/python-list
