定义打印日志的函数 defprint_log(thread_name):print(f"{thread_name}is printing log.") 1. 2. 这段代码定义了一个函数 print_log,用于打印线程名称 thread_name 打印日志的信息。 创建多个线程 thread1=threading.Thread(target=print_log,args=("Thread 1",))thread2=threading.Thread(target=print_log,...
Python 3.7 introduced several new functions, like thread_time(), as well as nanosecond versions of all the functions above, named with an _ns suffix. For example, perf_counter_ns() is the nanosecond version of perf_counter(). You’ll learn more about these functions later. For now, note...
$ ./daemon_thread.py Main : before creating thread Main : before running thread Thread 1: starting Main : wait for the thread to finish Main : all done The difference here is that the final line of the output is missing. thread_function() did not get a chance to complete. It was ...

https://realpython.com/python-print/#thread-safe-printing Printing isn’t thread-safe in Python. The print() function holds a reference to the standard output, which is a shared global variable. In theory, because there’s no locking, a context switch could happen during a call to sy...
