MultiProcessing in Python

  Learning Sections          show MultiProcessing in Python Multiprocessing in Python involves using the multiprocessing module to run multiple processes concurrently, taking advantage of multiple CPU cores. This module provides a higher level of concurrency than threading and is especially useful for CPU-bound tasks. Creating Processes You can create and start a new process by using the multiprocessing module: import multiprocessing def print_numbers (): for i in range ( 10 ): print ( i ) p1 = multiprocessing.Process ( target = print_numbers ) p1 . start () p1 . join () # Wait for the process to complete Using Process Pools The multiprocessing module provides a Pool class, which allows you to manage a pool of worker processes: from multiprocessing import Pool def square ( n ): return n * n with Pool ( 4 ) as pool : result = pool.map ( square , range (...

Instance variables vs Class variables in Python

  Learning Sections          show Instance variables vs Class variables in Python In Python, instance variables are variables that are bound to instances of a class, while class variables are variables that are bound to the class itself. Each instance of the class has its own copy of instance variables, while class variables are shared among all instances of the class. Instance variables are defined within methods of a class using the self keyword, while class variables are defined directly within the class body. Example: class Car : # Class variable wheels = 4 # Instance method to initialize instance variables def __init__ ( self , color ): # Instance variable self . color = color # Create instances of the Car class car1 = Car ( 'red' ) car2 = Car ( 'blue' ) # Access instance variables print ( car1 . color ) # Output: 'red' print ( car2 . color ) # Output: 'blue' # Acc...
