In some other typed languages, that is. E.g. in C++, OCaml, Haskell, F#, Kotlin, and Rust (a non-exhaustive list) you can have non-nullable strings, and other objects.

In Zig you have to mark variables as nullable when they are declared. If you try to assign null to any variable that doesn't have it marked as such the program won't compile.
Any nullable type has to be unwrapped before accessing the value, or again, won't compile.
It’s worth noting that even though the runtime allows nulls (i.e. None) anywhere, Python type checkers do distinguish between optional and mandatory types.
