This article introduces the knowledge of "how to transfer the list of python to the thread". In the operation of actual cases, many people will encounter such a dilemma, so let the editor lead you to learn how to deal with these situations. I hope you can read it carefully and be able to achieve something!

Description

1. All threads share global variables in one process, which makes it easy to share data among multiple threads.

2. The thread is a random modification of the global variable, which may lead to confusion between multiple threads (that is, thread is not safe).

Example

Import timefrom threading import Thread def work1 (nums): nums.append (44) print ("- in work1---", nums) def work2 (nums): # delay for a while Make sure that the things in the T1 thread are done. Time.sleep (1) print ("- in work2---", nums) g_nums = [11L22 in work2--- 33] T1 = Thread (target=work1, args= (g_nums,)) t1.start () T2 = Thread (target=work2, args= (g_nums,)) t2.start () "how the list of python is passed to the thread" ends here.
