Information isolation in the Python programming thread! It's called python!.

Hello everyone, 并发编程 go to the third article.

The first day of work, we should be more busy. Xiao Ming also, so today's content is very few. It will take just a few minutes to finish the study.

Yesterday we said that the execution of the control program is through message communication between the thread and the thread.

Finish the message communication, today to discuss how the downline thread 信息隔离 is done.

Note to everyone:

信息隔离, this is not the official name of the noun, nor is it widely circulated on the Internet. I was created for the convenience of understanding, you know the better.

. Preliminary understanding of information segregation

What's that 信息隔离 ?

For example, we have two threads, variables in thread A, and variable values in thread B cannot be shared. This is 信息隔离 .

You might say that the variable name is different.

Yes, if all the threads are not the same object instantiated by a class, it is indeed possible. We'll hang on to this question for the moment, I'll explain later.

So, how do we do that 信息隔离 ?

In Python, which provides threading.local this class, it is convenient to control the isolation of variables, even if the same variable, in different threads, its value is not shared.

Look in the code.

Friendly reminder:

The following code, to understand, may require you to understand the network programming related content of the socket. I have published a related article in the previous few days articles, the students who have no foundation can go to see the article first.
