While working with Pandas DataFrames, situations may arise where arithmetic operations between attributes are necessary. One such operation is deducting two attributes. In this guide, we will delve into three distinct techniques to deduct two attributes in a Pandas DataFrame: employing the `sub` method, utilizing the `apply` method combined with a lambda function, and leveraging the `subtract` function. Examples will aid in understanding these approaches. Method 1: Employing the `sub` method The `sub` method is an intrinsic Pandas function that facilitates direct deduction of one attribute from another. This technique is straightforward and effective for performing deductions between ... Read More

In the domain of machine learning or artificial intelligence models, data stands as the backbone. The way this data gets handled shapes the holistic performance of the model. This includes the indispensable task of segregating the dataset into learning and verification sets. While sklearn's train_test_split() is a frequently employed method, there could be instances when a Python aficionado might not have it at their disposal or is curious to grasp how to manually attain a similar outcome. This discourse delves into how one can segregate data into learning and verification sets without leaning on sklearn. We will bank on Python's ... Read More

Regular expressions, commonly known as re or Regex is a powerful tool for manipulating and searching for patterns in text. In Python, regular expressions are implemented using the re-module. A regular expression is a sequence of characters that define a search pattern. The pattern is used to match and manipulate text strings, which can be very useful for tasks such as data cleaning, parsing, and validation. To count the number of uppercase letters, lowercase letters, special characters, and numeric values in a string using regular expressions (regex), we can use specific patterns to match and count the desired characters.  Following ...

A half-diamond pattern is a geometric pattern that resembles the shape of a diamond, but only covers half of the diamond.  Diamond patterns can be created using loops in programming. By controlling the loops and the number of characters printed in each row, we can modify the pattern to achieve different shapes and arrangements. In this article, we will write a Python program that displays a half-diamond pattern of numbers with a star border. Input Output scenarios Let's explore some input-output scenarios for displaying the half-diamond pattern of numbers with a star border. Scenario 1 − Input: n = ... Read More

In the traditional IPv4 addressing scheme, IP addresses are divided into five classes: A, B, C, D, and E. Class E addresses, ranging from 240.0.0.0 to 255.255.255.255, are designated for particular purposes and are not intended for general use in the current internet infrastructure. As a result, Class E addresses are considered "reserved" and are not allocated or routable on the public internet. To determine if a given IPv4 address falls within one of the reserved IP address ranges defined by organizations like the Internet Engineering Task Force (IETF) and the Internet Assigned Numbers Authority (IANA), Python utilizes the is_reserved ...

In computer networking, IP addresses are used to uniquely identify devices connected to a network. IP addresses can be classified as either public or private. Public IP addresses are assigned to devices that are directly connected to the Internet. They are globally routable and can be accessed from anywhere on the Internet.  Private IP addresses, on the other hand, are used within private networks, such as local area networks (LANs) or home networks. These IP addresses are not directly accessible from the Internet. Private IP addresses are defined by certain reserved address ranges specified by the Internet Engineering Task Force ... Read More
