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

3I hope you are aware that tuples are immutable. You can do it, but that will create a new tuple (so references might break).Felix Kling– Felix Kling2011-03-04 22:54:50 +00:00Commented Mar 4, 2011 at 22:54

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.

As a very minor point, I'd probably reverse it and write it as
tuple(x if x != '' else '-' for x in tup), since the usual, expected case is non-empty.

@Adam Rosenfield: Or more succinctly:
tuple(x if x else '-' for x in tup)Adam Rosenfield
@Adeel: That won't work if OP wants to preserve other values interpreted as false, such as
False, 0, [], etc.Adeel Zafar Soomro
@Adam Rosenfield: You are absolutely correct. Despite the example provided by the OP, I erroneously assumed that the tuple is homogeneous.
