You cannot get rid of those if-else checks, but you can get rid of the nesting. For example:
if foo:
if bar:

if not bar:
return None
return foo + bar

Lately, I've been, I've been losing sleep
Dreaming about the things that we could be
But baby, I've been, I've been praying hard,

I'm creating an extension method that can be used on any type. The idea is that if this method is called, it checks if value is null. If null, it needs to return a default instance of the specified type.
