Stop Letting Python Functions Lie to You: Introducing explicit-result

The article discusses the explicit-result library, which provides a way to handle errors and return values in Python functions more explicitly. Here's a summary of its key features:

1. Result Type: The core concept is the Result type, which can either be an Ok(value) or an Err(error). This allows you to clearly indicate whether a function succeeded (returning a value) or failed (returning an error).

2. Function Signatures: By using Result, you can specify in your function signatures that the return type is not just a single value, but either a successful result (Ok) or an error (Err). This makes it clear to callers of the function what they need to handle.

3. Error Handling: Instead of raising exceptions or returning None for errors, you can now explicitly return an Err. This helps avoid silent failures and forces callers to deal with potential errors.

4. Zero Dependencies: The library is designed to be lightweight and have no external dependencies, making it easy to integrate into existing projects.

5. Full Typing Support: It's compatible with Python's type hinting system (PEP 561), allowing for better static analysis
