In Python, *args and **kwargs are special syntax that allow you to pass a variable number of positional and keyword arguments to functions. They are often used when you want to create flexible and generic functions that can accept a varying number of arguments. Here’s an explanation of each: When using *args and **kwargs, keep…
Parsing a string into a datetime object in Python is a common operation when you have date and time information stored as strings and you want to work with them as datetime objects. You can use the datetime.strptime() method (which stands for “string parse time”) to accomplish this. Here’s how you can do it step…
let’s create a real-world example of iterating over dates in Python. In this example, we’ll write a program that generates a list of dates within a specific range and then performs some action for each date. For simplicity, let’s say we want to print the dates in a given month. We will use the datetime…
Linked lists are a fundamental data structure in computer science and can be used in various real-world scenarios. In this tutorial, I’ll provide a simple example of implementing and using a singly linked list in Python, along with best practices. Scenario: Imagine you’re building a music playlist application, and you want to create a playlist…
The itertools library in Python is a powerful tool for working with iterators and generators. While itertools itself does not provide a direct “group by” function, you can use it to achieve similar functionality by combining it with other Python functions and data structures. We’ll walk through a tutorial with a real-world example of how…
Remote WebDriver in Selenium allows you to control a web browser on a remote server or machine. It’s particularly useful for distributed testing scenarios where you want to run tests on a different machine or on a cloud-based Selenium Grid. To use Remote WebDriver, you need to have the Selenium server (sometimes called the Selenium…

Certainly! Here are 10 common algorithms that you should be familiar with before your Python coding interview, along with Python code examples for each: These are just a few common algorithms you might encounter in a coding interview. Understanding these algorithms and being able to implement them in Python can be valuable during technical interviews.
Certainly! Let’s create a simple example to illustrate how to use lambda, map, and filter in Python. Let’s say we have a list of numbers and we want to perform some operations on them using map and filter along with lambda functions. In this example: When you run this code, you will get the following…
