Break and Continue Statements in Python

In Python, the break and continue statements are used to control the flow of loops. They provide greater control over how and when the loop should terminate or skip an iteration.

The Break Statement

The break statement is used to exit a loop prematurely when a certain condition is met. It stops the execution of the loop and moves to the code that follows the loop.


# Using break in a loop
for i in range(10):
    if i == 5:
        break
    print(i)

In this example, the loop will print numbers from 0 to 4 and then terminate when i equals 5.

The Continue Statement

The continue statement is used to skip the current iteration of a loop and continue with the next iteration. It effectively skips the rest of the code inside the loop for the current iteration only.


# Using continue in a loop
for i in range(10):
    if i == 5:
        continue
    print(i)

In this example, the loop will print numbers from 0 to 9, except for 5, which is skipped.

Using Break and Continue in While Loops

The break and continue statements can also be used in while loops to provide additional control over loop execution.


# Using break in a while loop
count = 0

while count < 10:
    print(count)
    count += 1
    if count == 5:
        break

In this example, the loop will print numbers from 0 to 4 and then terminate when count equals 5.


# Using continue in a while loop
count = 0

while count < 10:
    count += 1
    if count == 5:
        continue
    print(count)

In this example, the loop will print numbers from 1 to 10, except for 5, which is skipped.

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 (...

Introduction to Python Programming

  Learning Sections      show History of Python Python was created by Guido van Rossum and first released in 1991. He wanted to create a language that was easy to read and simple to use. The name "Python" comes from the British comedy series "Monty Python's Flying Circus". Key Features of Python Readability: Python's syntax is clear and easy to read. Ease of Learning: Python is straightforward, making it great for beginners. High-Level Language: Python handles much of the complexity of the computer’s operations. Interpreted Language: Python runs code line-by-line, which makes debugging easier. Dynamically Typed: You don’t need to declare variable types. Extensive Standard Library: Python has many built-in modules for various tasks. Portability: ...
