T1 = threading.Thread(target=print_hello) However, the function suspends a thread rather than the whole process in multithreaded programs.Įxample 4: sleep() in a multithreaded program import threading In case of single-threaded programs, sleep() suspends execution of the thread and process. The sleep() function suspends execution of the current thread for a given number of seconds. Visit this page to learn more about Multithreading in Python. Note that, t1 and t2 run concurrently and you might get different output. These threads are run using t1.start() and t2.start() statements. The above program has two threads t1 and t2. When you run the program, the output will be something like: T2 = threading.Thread(target=print_hi_three_times) T1 = threading.Thread(target=print_hello_three_times) Here's an example of a multithreaded Python program. A process can have one or more threads.Īll the programs above in this article are single-threaded programs. A process is the execution of those instructions.Ī thread is a subset of the process. To learn more, visit digital clock in Python shell.īefore talking about sleep() in multithreaded programs, let's talk about processes and threads.Ī computer program is a collection of instructions. Here is a slightly modified better version of the above program. When you run the program, the output will be something like: 02:10:50 PM Again, the current local time is computed and printed. In the above program, we computed and printed the current local time inside the infinite while loop. Result = time.strftime("%I:%M:%S %p", localtime) Since Python 3.5, the suspension time will be at least the seconds specified.Įxample 2: Python create a digital clock import time
