how to assign an alternate value to a variable if it is none

Question

I am just wondering if there is a way to assign a value/alternate value when it is None as below

conventional way

result = a if a else b

Expected way

result = assign(a,b)

PS: I could create a custom function but I would like to know if there is something by default already

    a = None
    b = "Hi"
    result = a or b
    print(result) # prints "Hi"

    a = "Hello"
    b = "Hi"
    result = a or b
    print(result) # prints "Hello"
