Also know, what does locking a thread do?
2 Answers. A lock allows you to force multiple threads to access a resource one at a time, rather than all of them trying to access the resource simultaneously. As you note, usually you do want threads to execute simultaneously. Most of the time, the threads won't try to write to the file all at once.
Also Know, is Python thread alive? Once the thread's activity is started, the thread is considered 'alive'. It stops being alive when its run() method terminates – either normally, or by raising an unhandled exception. The is_alive() method tests whether the thread is alive. Other threads can call a thread's join() method.
Correspondingly, what is start () in Python?
Start and stop a thread in Python. When a thread instance is created, it doesn't start executing until its start() method (which invokes the target function with the arguments you supplied) is invoked.
What is mutex in Python?
It is a mechanism to implement mutual exclusion to protect shared resources between processes or threads. A lock and a mutex are often used interchangeably however in Python the mutex is a module that defines a class to allow mutual exclusion by acquiring and releasing a lock object.
