Article Introduction：1.0.1 Preface This project (including code and comments) was recorded during my self-taught Rust. There may be inaccurate or unclear statements, please apologize. If you benefit from it, it's even better. 1.0.2 Why is RustRust reliable and efficient? Rust can replace C and C, with similar performance but higher security, and does not require frequent recompilation to check for errors like C and C. The main advantages include: memory security (preventing null pointers from dereferences, dangling pointers, and data contention). Thread-safe (make sure multi-threaded code is safe before execution). Avoid undefined behavior (e.g., array out of bounds, uninitialized variables, or access to freed memory). Rust provides modern language features such as generics

Article Introduction：Golang's static types check types at compile time, providing stronger security and maintainability, suitable for large projects; while Python has traditionally used dynamic types, and in recent years, the introduction of type prompts has enhanced flexibility and scalability. 1. Golang requires variable types to be determined when declared, and any type mismatch will be captured in the compilation stage; 2. Python checks the type at runtime, allowing variable types to change, but may cause problems that are difficult to debug in large systems; 3. Python3.5 supports type prompts, and type checks can be performed through tools such as mypy, but the interpreter itself does not enforce them; 4. Golang's static type makes the code more self-documentary, which is easy to understand and maintain; 5. Python's dynamic characteristics
