Generator Function: In Python, a generator is a function that allows you to create an iterator, an object that generates a sequence of values. A generator function is defined using the keyword yield, rather than return. When a generator function is called, it returns a generator object, which can be used to iterate over the […]

The yield keyword in Python is used in the body of a function like a return statement, but when a function with a yield statement is called, it returns a generator object instead of a single value. The generator can then be iterated over to retrieve the values produced by the yield statement one at […]

What is an Iterable? In Python, an iterable is an object that can be looped over, such as a list, tuple, or string. An iterator is an object that represents a stream of data, and it can be used to traverse through all the elements of an iterable. The built-in function iter() can be used […]

Because Python lacks a main() function, when the command to run a Python program is given to the interpreter, the code at level 0 indentation is executed. However, it will first define a few special variables. One such special variable is __name__. If the source file is run as the main program, the interpreter assigns […]

Barrier object in Python is used to synchronize the execution of multiple threads. When a thread reaches a barrier point, it calls the wait() function, and the barrier keeps track of the number of threads that have reached the barrier. When the number of threads that have reached the barrier is equal to the number […]

A Condition object in Python is a synchronization object that allows multiple threads to wait for a specific condition to be met. It is similar to a Lock, but it will enable you to synchronize threads not only on the acquisition of the lock, but also on the release of the lock. To better understand […]

Timer objects are used to schedule a function to be executed at a certain time in the future. The timer is started with a specified number of seconds to wait before executing the function, but the actual time when the function is executed will depend on the availability of system resources and the scheduling of […]

RLock (re-entrant lock) is a type of lock that allows the holder of the lock to acquire it multiple times without causing a deadlock. This can be useful in situations where a thread needs to acquire the same lock multiple times while performing some operation. Note: If a code can be safely called again, it […]

What is a Lock Object? In Python, a threading.Lock object is used to synchronize the execution of threads. It can protect critical sections of code that should not be executed concurrently. When a thread acquires a lock, it blocks other threads from entering the critical section until it is released. Syntax for creating a Lock […]
