Example 1: threading python example
import threading
import time
def loop1_10():
for i in range(1, 11):
time.sleep(1)
print(i)
threading.Thread(target=loop1_10).start()
import threading
import time
class MyThread(threading.Thread):
def run(self):
print("{} started!".format(self.getName()))
time.sleep(1)
print("{} finished!".format(self.getName()))
def main():
for x in range(4):
mythread = MyThread(name = "Thread-{}".format(x))
mythread.start()
time.sleep(.9)
if __name__ == '__main__':
main()
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)
