What is the most Pythonic way to provide a fall-back value in an assignment?

Question

In Perl, it\'s often nice to be able to assign an object, but specify some fall-back value if the variable being assigned from is \'undef\'. For instance:

my $x         


        

Answer 1

first you can do your full-on with a ternary:

a = y if x is None else x

but it doesn't solve your problem. what you want to do is more closely implemented with:

try:
    a = x
except:
    a = y
