how about splitting on "_", joining pairs with ":", and finally joining the result with "," ? >>> s1 = "hi_cat_bye_dog" >>> s1 = s1.split("_") >>> s1 ['hi', 'cat', 'bye', 'dog'] >>> s1 = [s1[i]+":"+s1[i+1] for i in range(0,len(s1),2)] >>> s1 ['hi:cat', 'bye:dog'] >>> s1 = ",".join(s1) >>> s1 'hi:cat,bye:dog' (there are many other ways to do it, but the above 3-liner is short and straightforward. note the use of range() to step over every other item in the list) </F> -- http://mail.python.org/mailman/listinfo/python-list
