python multiple threading 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: multithreading python
class FakeDatabase:
def __init__(self):
self.value = 0
self._lock = threading.Lock()
def locked_update(self, name):
logging.info("Thread %s: starting update", name)
logging.debug("Thread %s about to lock", name)
with self._lock:
logging.debug("Thread %s has lock", name)
local_copy = self.value
local_copy += 1
time.sleep(0.1)
self.value = local_copy
logging.debug("Thread %s about to release lock", name)
logging.debug("Thread %s after release", name)
logging.info("Thread %s: finishing update", name)
