Python threading.setprofile() Method

setprofile() is an inbuilt method of the threading module in Python. It is used to set a profile function for all the threads that are created by the threading module. The func function is passed to sys.profile() for each method.

Module:

    import threading

Syntax:

    setprofile(func)

Parameter(s):

• func: It is a required parameter, which is passed to sys.setprofile() for each thread. This function is executed before the run() method.

Return value:

The return type of this method is <class 'NoneType'>, it does not return anything. It sets a profile function for all the threads.

Example:

# Python program to explain the use of 
# setprofile()  method in Threading Module

import time
import threading

def trace_profile(): 
    print("Current thread's profile")
    print("Name:", str(threading.current_thread().getName()))
    print("Thread id:", threading.get_ident())

def thread_1(i):
    time.sleep(5)
    threading.setprofile(trace_profile())
    print("Value by Thread-1:",i)
    print()
    
def thread_2(i):
    threading.setprofile(trace_profile())
    print("Value by Thread-2:",i)
    print()
    
def thread_3(i):
    time.sleep(4)
    threading.setprofile(trace_profile())
    print("Value by Thread-3:",i)
    print()
    
def thread_4(i):
    time.sleep(1)
    threading.setprofile(trace_profile())
    print("Value by Thread-4:",i)
    print()

# Creating sample threads 
threading.setprofile(trace_profile())
thread1 = threading.Thread(target=thread_1, args=(1,))
thread2 = threading.Thread(target=thread_2, args=(2,))
thread3 = threading.Thread(target=thread_3, args=(3,))
thread4 = threading.Thread(target=thread_4, args=(4,))

# Starting the threads
thread1.start()
thread2.start()
thread3.start()
thread4.start()
