What are immutable objects in Python and how do they ensure thread safety?

Immutable objects in Python are objects whose state cannot be modified after they are created. Examples include tuples and strings.

How do immutable objects help with thread safety?

They help with thread safety because multiple threads can access immutable objects without the risk of one thread modifying the object while another is reading it.

Can you give an example of an immutable object?

Sure! A tuple is an example of an immutable object. Once you create a tuple, you cannot change its elements.

Are there any downsides to using immutable objects?

Yes, one downside is that if you need to change the data, you have to create a new object, which can lead to increased memory usage.
