In fact, I run and debug these codes, as shown below, both in IDLE (Python 3.5.2 shell) and in Pycharm Community Edition 2017.2. But when I run the code many times, I find that some issues confuse me. The code run in pycharm generates this result:
- Thread-3 Processing One Thread Processing 1 Thread-3 processing Three Thread Processing 2 Thread-3 processing Five Thread-1 processing Six Thread Processing-2 Seven Thread-1 processing Eight
Executing code in pycharm generates this result:
- Processing Thread-1 One Thread-2 processing Two Thread-3 processing Three Processing thread 1 Thread-2 processing Five Thread-3 processing Six Processing Thread-1 Seven Thread-2 processing Eight
As you can see, "1 3 2 3 1 2 1" and "2 3 1 2 3 1 2". I run many times and find it. So I just want to know why the stream method is different in different IDEs? And could you tell me some good directions for exploring a topic in Python3?
