![Create a thread - Threading Module
Follow below steps:
Construct a subclass from the <Thread> class.
Override the <__init__(self [,args])> method to provide arguments.
override the <run(self [,args])> method to code the actual required logic of the thread.
When start is called on instance of Thread subclass,it eventually calls overridden run method.](https://image.slidesharecdn.com/multithreading-170602072056/85/Python-Training-in-Bangalore-Multi-threading-Learnbay-in-7-320.jpg)

- 2. What are threads? Thread is smallest unit that can be scheduled in an operating system. Process vs Thread? Multiple threads within a process share the same data space with the main thread Threads sometimes called light-weight processes and they do not require much memory overhead Create a Process: Code: https://repl.it/IIpm/0
- 3. Threading in Python There are two modules which support the usage of threads in Python: Thread Threading (We should use threading model instead of thread) The module "thread" treats a thread as a function, while "threading module " is implemented in OOPS way, i.e. every thread corresponds to an object.
- 4. Thread Module we can use the function thread.start_new_thread: thread.start_new_thread(function, args) Method starts a new thread and return its identifier.Thread starts and execute the handler function “function” with args as argument. “Args” should be a tuple. Code Example: https://repl.it/IIqg/3
- 5. Thread Lock Discuss about atomic operation.What happens to global variable in case of multithreading. Problem in this code: https://repl.it/IIz1/0 Use lock_object = thread.allocate_lock() And lock.acquire() and lock.release() Code example: https://repl.it/IIyL/2
- 6. Threading Module Threading module builds on the low-level features of thread to make working with threads even easier and threads are implemented as objects. Basic Example: https://repl.it/IJAB/3
- 7. Create a thread - Threading Module Follow below steps: Construct a subclass from the <Thread> class. Override the <__init__(self [,args])> method to provide arguments. override the <run(self [,args])> method to code the actual required logic of the thread. When start is called on instance of Thread subclass,it eventually calls overridden run method.
