Threads join() question

[adam2020]

Thread.join() will stop the current thread, until the referenced thread has completed. In your example, t1.join() would stop the main thread, while both t1 and t2 continue running. Once t1 completes, the main thread would resume. The very next line, t2.join(), would again halt the main thread until t2 had completed. At that point, you had already guaranteed that t1 had completed, so the only running thread would be t2.

Once t2 completes, the main thread would resume. At the next instruction, print("bye"), the main thread is the only thread still running.

thanks nilamo,

that makes sense, but lets suppose t2 somehow finished before t1, t1.join() finishes now the next line will be t2.join() but t2 has already finished running also, what would happen?

thanks
