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: multithreading in python
from multiprocessing.pool import ThreadPool
def stringFunction(value):
my_str = 3 + value
return my_str
def stringFunctio(value):
my_str = 33 + value
return my_str
pool = ThreadPool(processes=1)
thread1 = pool.apply_async(stringFunction,(8,))
thread2 = pool.apply_async(stringFunctio,(8,))
return_val = thread1.get()
return_val1 = thread2.get()
Example 4: python threading
def myFunction(x, y):
pass
x = threading.Thread(target=myFunction, args=(x, y))
x.start()
Example 5: how to execute program with multithreading python
#!/usr/bin/python
import thread
import time
# Define a function for the thread
def print_time( threadName, delay):
count = 0
while count < 5:
time.sleep(delay)
count += 1
print "%s: %s" % ( threadName, time.ctime(time.time()) )
# Create two threads as follows
try:
thread.start_new_thread( print_time, ("Thread-1", 2, ) )
thread.start_new_thread( print_time, ("Thread-2", 4, ) )
except:
print "Error: unable to start thread"
while 1:
pass
Example 6: python 2.7 multithreading
from multiprocessing.pool import ThreadPool as Pool
pool_size = 10
pool = Pool(pool_size)
results = []
for region, directory_ids in direct_dict.iteritems():
for dir in directory_ids:
result = pool.apply_async(describe_with_directory_workspaces,
(region, dir, username))
results.append(result)
for result in results:
code, content = result.get()
if code == 0:
