Q:

replace empty string(s) in tuple

Is there an easy way (hopefully a one liner) to replace '' with something like '-'?
Many thanks.
tup = (1,2,'ABC','','','','text')

A:

How about the following?
 tuple('-' if x == '' else x for x in tup)

As Felix Kling comments, tuples are immutable, so the best you can do is to return a new one.
