The ternary operator in many languages works like so:

x = f() ? f() : g()

Where if f() is truthy then x is assigned the value of f(), otherwise it is assigned the value of g(). However, some languages have a more succinct elvis operator that is functionally equivalent:

x = f() ?: g()

In python, the ternary operator is expressed like so:

x = f() if f() else g()

But does python have the more succinct elvis operator?

Maybe something like:

x = f() else g() # Not actually valid python

Yes

Python does have the elvis operator. It is the conditional or operator:

x = f() or g()

f() is evaluated. If truthy, then x is assigned the value of f(), else x is assigned the value of g().
