replace empty string(s) in tuple

Question

Is there an easy way (hopefully a one liner) to replace \'\' with something like \'-\'?
Many thanks.

tup = (1,2,\'ABC\',\'\',\'\',\'\',\'text\')
<         


        

Answer 1

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.
