Using the threading module, the print_numbers and print_letters functions are executed concurrently in separate threads.

Both functions run simultaneously, resulting in numbers and letters being printed in an interleaved manner.
thread1.join() and thread2.join() ensure the main thread waits until both of these threads complete.
