Locks. Lock s are perhaps the simplest synchronization primitives in Python. A Lock has only two states — locked and (surprise) unlocked. It is created in the unlocked state and has two principal methods — acquire() and release() .
Keeping this in consideration, what is a thread lock python?
Locks. Locks are the most fundamental synchronization mechanism provided by the threading module. At any time, a lock can be held by a single thread, or by no thread at all. If a thread attempts to hold a lock that's already held by some other thread, execution of the first thread is halted until the lock is released.
Also question is, what is lock thread?
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. However, imagine that you have two threads and they are both writing to the same file.
File Modes in Python This Mode Opens file for writing. If file does not exist, it creates a new file. Open file in append mode. If file does not exist, it creates a new file.
