How can I use type hints in Python 3.10 with legacy code?
You can gradually introduce type hints in your legacy code by starting with function signatures. Use the typing
module for complex types.
What if my legacy code has many dynamic types?
In that case, you can use Any
from the typing
module to indicate that a variable can be of any type, allowing for flexibility.
Are there tools to help me add type hints automatically?
Yes, tools like mypy
and pyright
can help analyze your code and suggest type hints. Additionally, IDEs like PyCharm offer features to assist with this.
Can type hints improve my code's performance?
