Killing threads is not considered to be good practice. Python doesn't provide the ability to kill a thread by calling a method or function, and this should be a hint that killing threads isn't something you want to be doing.

One reason is that a thread might have children—threads spawned from within the thread itself—which would be orphaned when their parent dies. Another reason could be that if the thread you're killing is holding a resource that needs to be closed properly, you might prevent that from happening and that could potentially lead to problems.

Later, we will see an example of how we can work around these issues.
