Hi All,

can someone help me how to call python function with args in multithreading. the below code is not able to create multiple threads.

import threading
lock = threading.Lock()

def first_function():
for i in range(5):
lock.acquire()
print (‘lock acquired’)
print (‘Executing the first funcion’)
lock.release()

def second_function():
for i in range(5):
lock.acquire()
print (‘lock acquired’)
print (‘Executing the second funcion’)
lock.release()

if name==“main”:
thread_one = threading.Thread(target=first_function)
thread_two = threading.Thread(target=second_function)

print("Thread start time:-", datetime.datetime.now())
print("Thread1 start time:-", datetime.datetime.now())
thread_one.start()
print("Thread1 end time:-", datetime.datetime.now())
print("Thread2 start time:-", datetime.datetime.now())
thread_two.start()
print("Thread2 end time:-", datetime.datetime.now())

thread_one.join()
thread_two.join()
2

Use the args keyword:

tasks = []
t = threading.Thread(target=worker, args=(tasks,))

I recommend you take a look at RealPython’s intro to threading:
