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.
Additionally, how do you stop a race condition in python? Lock is used to guard against race condition. If thread t1 has acquired the lock before performing a set of operations, no other thread can perform the same set of operation until t1 releases the lock.
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.
