Does golang have the equivalent of this Python short circuit idiom `z = x or y`

Question

In Python z = x or y can be understood as assign z as if x is falsey, then y, else x, is there a similar idiom in golang?

Specifically the two variables on the right are strings, I'd like to assign the first if it's non-emtpy, otherwise the second.

Are you asking about a ternary operator? If so, see here for the idiomatic way to do conditionals. http://stackoverflow.com/questions/19979178/what-is-idiomatic-gos-equivalent-of-cs-ternary-operator — Antiga, Dec 07 '15 at 22:35
Go is statically-typed. There isn't a concept of "falsey" in any type other than `bool`. — newacct, Dec 08 '15 at 02:46

No, you have to use if/else:

s1, s2 := "", "hello"
var x string

if s1 == "" {
    x = s2
} else {
    x = s1
}
