Can you express value semantics in Python, or is everything still passed by mutable reference still and duck-typed at runtime? I’m being flip, and I like Python

Can you express value semantics in Python, or is everything still passed by mutable reference still and duck-typed at runtime? I’m being flip, and I like Python for some things, but for large robust performant software I find C++ way easier to work with as it works with me not against me to wrangle complexity.
