The utilization of data structures in Python presents a perplexing and convoluted method of depicting numbers, strings, and other Python objects in a collection of values. Python's built-in data structures, such as lists, tuples, and sets, are captivating and exhibit distinctive traits that differentiate them from one another. These data structures possess an extraordinary capacity to hold groups of objects, rendering them one of a kind. In this article, we will see which among the three fits best with examples. List Items can be changed, added to, or taken out of after they are made. It can also be ... Read More
Methods are important when it comes to Python's object-oriented programming (OOP). They are crucial for isolating functionality within a class and giving things the ability to carry out particular functions. However, two OOP concepts—method overloading and method overriding—can occasionally cause misunderstanding. The distinctions between these two ideas and their applications in Python will be discussed in this article. Syntax Using the "def" verb, the method's name, arguments, and body are all required to define a method in Python. def method_name(parameter1, parameter2, ...): # method body return value Comparison Table Method ...

Data that only includes a few values is referred to as categorical data, often known as categories or levels and it is described in two ways - nominal or ordinal. Data that lacks any intrinsic order, such as colors, genders, or animal species, is represented as nominal categorical data while ordinal categorical data refers to information that is naturally ranked or ordered, such as customer satisfaction levels or educational attainment. We will go through how to handle categorical data in Python in this tutorial. Setup pip install pandas pip install scikit-learn pip install category_encoders Categorical data is often ... Read More
Flask offers a number of features, such as database access, processing of user input, and dynamic data delivery. An effective and user-friendly online application may be made using HTML and simple Python coding. Python gives us the ability to work with data and provide consumers tailored experiences, while Flask makes it easier to create web applications. The data item is also shown in the browser using HTML. You'll have a working Fun Fact Generator web application at the conclusion of this lesson. Setup Make sure we have the necessary frameworks and libraries installed before we start. The only requirements ... Read More
The fromtimestamp() function of the Python datetime.date class is useful for converting a timestamp into a date object. A timestamp essentially denotes the duration since the epoch (which took place on January 1, 1970, 00:00:00 UTC). To help you understand the fromtimestamp() function's practical uses, we'll go over the syntax and coding practices involved in utilizing it in this blog article. We'll also include different Python code samples. Syntax datetime.date.fromtimestamp(timestamp) The method returns a date object that represents the timestamp and only requires a single input, the timestamp value in seconds. You must use the class name to access ... Read More
This technique is used to navigate forward in a web browser's history and allows Selenium to move forward in the browser's history page executing any new navigation commands. This Forward Driver Method in Selenium Python can improve the efficiency and accuracy of your automated testing scripts. which allows you to quickly move between. Setup Firefox Executable Download the Firefox browser installer from here Once downloaded, install the browser and an exe file will be placed automatically in C:\Program Files\Mozilla Firefox\firefox.exe. We will be needing it later. Gecko Driver Windows Users can download the gecko ... Read More
An open-source program used to automate web browsers is called Selenium Webdriver. It offers a platform-independent testing framework for web applications on many platforms and browsers. With the use of deep learning and computer vision algorithms, the food identification API Caloriemama can recognise different foods and their nutritional values from a single photograph. In this guide, we'll look at how the Selenium Webdriver automates the process of uploading photographs and retrieving the results, making it simple for developers to include food recognition functionality into their apps and provide consumers with correct nutritional information. Setup Firefox Executable Download the ... Read More
Calculating the average of a collection of data is done using the statistical measure of central tendency known as the harmonic mean. The harmonic mean of a given collection of integers may be determined in Python using the harmonic mean() function. Python 3.0 and subsequent versions of the language come with the statistics module, which has this function. We'll go through the harmonic_mean() function in Python's syntax, code methodology, and uses. Syntax The statistics module is included in Python 3.0 and later versions, so no installation is required. To use the harmonic_mean() function, simply import the statistics module in your ...

A timezone is a geographic area where all the clocks are set to the same standard time, but owing to political choices, historical time zone changes, disparities in daylight saving time, and other factors, various locations may have distinct time offsets. A collection of classes for working with dates, times, and timezones are provided by the Python datetime module and pytz library, respectively. Timezone management in software development is crucial since it affects how accurately programmes provide results. With the help of three annotated examples, this article will examine how to manage timezones in Python using the datetime and pytz ... Read More
Universally Unique Identifier (UUID) is a 128-bit value that is used to uniquely identify objects or entities. UUID is widely used in computer systems for generating unique IDs for objects, documents, and data records. In Golang, we can generate UUID using the "github.com/google/uuid" package. Installing the "github.com/google/uuid" Package Before we can generate UUID in Golang, we need to install the "github.com/google/uuid" package. To install this package, run the following command in the terminal − go get github.com/google/uuid Generating UUID in Golang Once we have installed the "github.com/google/uuid" package, we can use the "uuid" package to generate UUIDs. Here's an ... Read More
