What are the best practices for using comparison operators in Python?

When using comparison operators in Python, it's important to ensure clarity and readability. Use parentheses to group conditions when necessary, and prefer '==' for equality checks instead of 'is' unless comparing to singletons like None.

Can you give me an example of using comparison operators?

Sure! For instance, you can compare two numbers like this: if a < b:. This checks if 'a' is less than 'b'.

What about chaining comparison operators?

Chaining is a powerful feature in Python. You can write conditions like if a < b < c: which checks if 'a' is less than 'b' and 'b' is less than 'c' in a single statement.

Are there any common mistakes to avoid?

Yes, a common mistake is using '==' to compare floating-point numbers due to precision issues. Instead, consider using a tolerance level for comparisons.
