Threading python3 code example

Example 1: create new thread python

from threading import Thread
from time import sleep

def threaded_function(arg):
    for i in range(arg):
        print("running")
        sleep(1)


if __name__ == "__main__":
    thread = Thread(target = threaded_function, args = (10, ))
    thread.start()
    thread.join()
    print("thread finished...exiting")

Example 2: threading python example

# A minimal threading example with function calls
import threading
import time

def loop1_10():
    for i in range(1, 11):
        time.sleep(1)
        print(i)

threading.Thread(target=loop1_10).start()

# A minimal threading example with an object
import threading
import time


class MyThread(threading.Thread):
    def run(self):                                         # Default called function with mythread.start()
        print("{} started!".format(self.getName()))        # "Thread-x started!"
        time.sleep(1)                                      # Pretend to work for a second
        print("{} finished!".format(self.getName()))       # "Thread-x finished!"

def main():
    for x in range(4):                                     # Four times...
        mythread = MyThread(name = "Thread-{}".format(x))  # ...Instantiate a thread and pass a unique ID to it
        mythread.start()                                   # ...Start the thread, run method will be invoked
        time.sleep(.9)                                     # ...Wait 0.9 seconds before starting another

if __name__ == '__main__':
    main()

Example 3: threading python

import threading
import time

def thread_function(name):
     print(f"Thread {name}: starting")
     time.sleep(2)
     print(f"Thread {name}: finishing")
 
my_thread = threading.Thread(target=thread_function, args=(1,))
my_thread.start()
time.sleep(1)
my_second_thread = threading.Thread(target=thread_function, args=(2,))
my_second_thread.start()
my_second_thread.join() # Wait until thread finishes to exit

Example 4: python thread function

x = threading.Thread(target=thread_function, args=(1,), daemon=True)
x.start()
# x.join()

Example 5: how to thread python

import threading, time

def worker():
    """thread worker function"""
    print('Worker')
    return

threads = []
for i in range(5):
    t = threading.Thread(target=worker)
    threads.append(t)
    t.start()
    print('Thread')

Example 6: python threading

def myFunction(x, y):
  pass

x = threading.Thread(target=myFunction, args=(x, y))
x.start()
