What are the best practices for using constants in Python?

In Python, constants are typically defined using uppercase letters. It's a good practice to use a single underscore for multi-word constants, like MAX_SIZE or DEFAULT_TIMEOUT.

Should I use constants in classes or modules?

It depends on the context. If the constant is related to a specific class, defining it within the class is appropriate. For general constants, module-level constants are better.

How can I ensure that my constants are not modified?

While Python doesn't have true constants, you can use naming conventions and document your code to indicate that certain variables should not be changed. Additionally, using a class with properties can help enforce immutability.

Are there any libraries that help manage constants?

Yes, libraries like const can help manage constants in a more structured way, allowing you to define and access them easily.
