What are the best practices for dynamic typing in programming?

Dynamic typing allows variables to hold values of any type, but it can lead to runtime errors. Best practices include using clear naming conventions, writing unit tests, and leveraging type hints when possible.

Can you explain why type hints are useful in dynamically typed languages?

Type hints improve code readability and help catch errors early by providing hints about what type a variable should be. They also assist IDEs in offering better autocompletion and error checking.

What are some common pitfalls of dynamic typing?

Common pitfalls include runtime errors due to unexpected types, difficulty in maintaining large codebases, and challenges in debugging. It's essential to be cautious and validate types when necessary.

How can I validate types in a dynamically typed language?

You can validate types using built-in functions, assertions, or libraries designed for type checking. For example, in Python, you can use the isinstance() function to check types before performing operations.
