technology and computing programming languagesWhat is Lock Python?
lockspython. Race condition is a significant problem in concurrent programming. The condition occurs when one thread tries to modify a shared resource at the same time that another thread is modifying that resource – t?his leads to garbled output, which is why threads need to be synchronized.
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.
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.
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.
