alternative to python

I've heard that Rust is largely replacing C. Assembly I think is useful for learning more about hardware, which is great, but shouldn't be misunderstood as (generally) useful. JS is a necessary evil right now  :(

So I've been reading the Rust Book (https://doc.rust-lang.org/book/), and Rust is a crazy impressive language.  Everything is immutable by default, and objects have a sense of 'ownership' and scope, which the compiler enforces, which makes cleanup easy.  What I like is the way error handling is done... a given function can only raise a single type of error, if you want to return more than one, you need to create a new error type to represent it.  If a function CAN return an exception, the compiler FORCES you to handle it (even if handling it is just re-raising it).

And almost everything is an expression.  It almost feels like ruby, in that the last line of a function is that function's return value, even if you don't explicitly use the keyword "return".  And almost everything returns a value... like match (their switch/case), or if.  So you can do things like...

// this is a complete program
// writes "The value: foobar" to console

fn main() {
    let spam = "eggs";
    let some_value = match spam {
        "12" => "twelve",
        "eggs" => "foobar",
        _ => "default value"
    };

    println!("The value: {}", some_value);
}
