Introduction The `os` module in Python provides a way of using operating system dependent functionality like reading or writing to the file system. One of the most common tasks when working with files and directories is navigating through directory structures, creating new directories, and deleting existing ones. In this tutorial, we will focus on how […]
Introduction String interpolation is a technique used to embed variables directly into string literals. It is a common operation in any programming language and Python provides several ways to perform string interpolation. In this tutorial, we will explore different methods of string interpolation in Python and their advantages and disadvantages. We will also discuss the […]
Introduction In computer science, a priority queue is an abstract data type that is similar to a regular queue or stack, but each element in the queue has a priority associated with it. Elements with higher priority are dequeued first, while those with lower priority are dequeued later. Priority queues are commonly used in algorithms […]
Introduction In Python, a tuple is an immutable sequence of elements, meaning that once created, its contents cannot be modified. The namedtuple, on the other hand, is a subclass of the tuple class that allows you to give names to each position in the tuple. This makes it easier to work with tuples by allowing […]
Introduction Euler’s number, also known as the mathematical constant e, is an important number in mathematics and has many practical applications in fields such as finance and physics. It is defined as the limit of (1 + 1/n)^n as n approaches infinity. In this section, we will learn how to calculate Euler’s number using Python […]
Introduction If you have been working with Python, you may have come across the `__init__.py` file in various directories. This file is often found in Python packages and it plays an important role in how the package is imported and used within our code. In this beginner’s guide, we will take a closer look at […]
Introduction MySQL is one of the most popular open-source relational database management systems. It is widely used in various web applications, and Python provides a module called “mysql-connector-python” that allows us to connect to MySQL server and perform various database operations. In this tutorial, we will learn how to connect to MySQL server in Python […]
Introduction In today’s world, data is considered the new oil. The ability to store, manage and analyze large amounts of data is crucial for businesses to make informed decisions. PostgreSQL is one of the most popular open-source relational database management systems used to store and manage data. It is known for its stability, scalability and […]
Introduction Python is a powerful programming language that is widely used in various industries, including data science, web development, and automation. One of the key strengths of Python is its ability to connect to various databases, including SQL Server. In this tutorial, we will explore how to connect to SQL Server in Python. Before we […]
Introduction In Python, bitwise operators are used to perform operations on individual bits of binary numbers. These operators include AND, OR, NOT, XOR, left shift, and right shift. In this tutorial, we will focus on the XOR operator and its usage in Python programming. XOR (exclusive OR) is a binary operator that compares two binary […]
