Comments Off on Stack Abuse: How to Create, Move, and Delete Files in Python, Python, by admin.

Introduction

Handling files is an entry-level and fundamental skill for any programmer. They’re very commonly used to store application data, user configurations, videos, images, etc. There are a countless number of use-cases for files in software applications, so you’d be smart to make yourself deeply familiar with the tasks of manipulating files. These tasks could include (among others) creating, deleting, and moving files.

In this article, we’ll cover the process of working with files using the Python programming language. The … Read the rest

Real Python: Python "while" Loops (Indefinite Iteration)

Comments Off on Real Python: Python "while" Loops (Indefinite Iteration), Python, by admin.

Iteration means executing the same block of code over and over, potentially many times. A programming structure that implements iteration is called a loop.

In programming, there are two types of iteration, indefinite and definite:

  • With indefinite iteration, the number of times the loop is executed isn’t specified explicitly in advance. Rather, the designated block is executed repeatedly as long as some condition is met.

  • With definite iteration, the number of times the designated block will be

Stack Abuse: Applying Wrapper Methods in Python for Feature Selection

Comments Off on Stack Abuse: Applying Wrapper Methods in Python for Feature Selection, Python, by admin.

Introduction

In the previous article, we studied how we can use filter methods for feature selection for machine learning algorithms. Filter methods are handy when you want to select a generic set of features for all the machine learning models.

However, in some scenarios, you may want to use a specific machine learning algorithm to train your model. In such cases, features selected through filter methods may not be the most optimal set of features for that specific algorithm. … Read the rest

Python Celery – Weekly Celery Tutorials and How-tos: Quick Guide: Custom Celery Task Logger

Comments Off on Python Celery – Weekly Celery Tutorials and How-tos: Quick Guide: Custom Celery Task Logger, Python, by admin.

I previously wrote about how to customise your Celery log handlers. But there is another Celery logger, the celery.task logger. The celery.task logger is a special logger set up by the Celery worker. Its goal is to add task-related information to the log messages. It exposes two new parameters:

  • task_id
  • task_name

This is useful because it helps you understand which task a log message comes from. The task logger is available via celery.utils.log.
