Note that Python supports type annotations in its syntax, but the interpreter will just ignore them as they are meant to be used by external tools such as ruff:

Note that Python supports type annotations in its syntax, but the interpreter will just ignore them as they are meant to be used by external tools such as ruff: https://github.com/astral-sh/ruff https://github.com/astral-sh/ruff I've had a good experience developing small to medium sized Python programs/scripts using type annotations plus ruff connected to my editor through its LSP (Language Server Protocol). It helps a lot, and I don't like to write Python without it. You can create types from literal values and use union types, which I feel makes it more pleasant than Go's type system for example.
