Yes, in Python, you can run two or more threads simultaneously using the threading module.

Example of creating and starting two threads:

import threading
import time

def worker(name):
    for i in range(3):
        print(f"Thread {name} is working {i}")
        time.sleep(1)

thread1 = threading.Thread(target=worker, args=("A",))
thread2 = threading.Thread(target=worker, args=("B",))

thread1.start()
thread2.start()

thread1.join()
thread2.join()
print("All threads are finished")

However, keep in mind that due to GIL (Global Interpreter Lock), in standard CPython, threads do not execute in parallel on multiple cores for CPU-bound tasks, but for I/O-bound tasks (like network requests, file reading), multithreading works efficiently.
