default value in list comprehension

just a quick one,

Is it possible to achieve a default value in a list comprehension
where the if-clause is false?

Ie, something similar to:

[ a for a in b if something(a) else 'default' ]

the idea being that, rather than skip a value if the if-clause is
false, to place a default value at that position in the returned list
