Ruby:

a || b

(no return as last line is returned implicitly, no semicolon)

EDIT: As pointed out in the comments, this is not strictly equivalent, as it will return b if a is false as well as if it's nil (these are the only two falsy values in Ruby).

Python:

return a or b

i like it because it reads like a sentence so it somewhat makes sense

and you can make it more comprehensive if you want to:

return a if a is not None else b

This diverges from the OP code snippets if a has the value False.
