Can I change types during runtime in dynamic typing?

Can I change the type of a variable during runtime in a dynamically typed language?

Yes, in dynamically typed languages like Python or JavaScript, you can change a variable's type at runtime.

Can you give me an example of that?

Sure! In Python, you can do something like this: x = 10 (integer), then x = 'Hello' (string).

Are there any downsides to changing types like this?

Yes, it can lead to runtime errors if you're not careful, as the type of the variable may not match the expected type in operations.

How can I avoid these errors?

You can use type checking or assertions to ensure the variable is of the expected type before performing operations.
