An example of an AI chatbot conversation about adding type hints in legacy Python code.
How can I add type hints to my legacy Python code?
You can start by identifying the function signatures and variable types in your code. Then, use the syntax introduced in Python 3.10 to annotate them.
What if I don't know the types of some variables?
In that case, you can use the Any type from the typing module as a placeholder. This allows you to gradually refine your type hints later.
Are there tools to help me with this process?
Yes, tools like mypy can help you check type hints and identify areas where you might need to add or adjust them.
Can I add type hints to classes as well?
Absolutely! You can annotate class attributes and methods in a similar way, enhancing the readability and maintainability of your code.
