In this article, we will learn to code a vending machine in Python. Vending Machine with Python Each item will have its product id, product name, and product cost properties stored in a dictionary. a list that is currently empty but will later be filled with all the selected items. The value of a "run" variable is True up until the point at which the user decides they are satisfied and do not wish to buy any more products; at that point, the value is changed to False, and the loop ends. We will now try to understand the Python ... Read More
In this article, we will show how to sort a list of dictionaries by the values of the dictionary in Python. Sorting has always been a useful technique in everyday programming. Python's dictionary is often used in a wide range of applications, from competitive to developer-oriented (example-handling JSON data). It can be useful in certain situations to be able to filter dictionaries based on their values. Below are the 2 methods to accomplish this task − Using sorted() and itemgetter Using sorted() and lambda functions What is a Dictionary? Dictionaries are Python's version of an associative array data ... Read More
In this article, we will learn what is a .data file and how to read a .data file in python. What is a .data file? .data files were created to store information/data. Data in this format is frequently placed in either a comma-separated value format or a tab-separated value format. In addition to that, the file may be in binary or text file format. In that case, we'll have to find another way to access it. For this tutorial, we will be working with.csv files, but first, we must determine whether the file's content is text or binary. Identifying data ... Read More
In this article, we will discuss whether or not we can get a job with a Python certificate, as well as what types of jobs we can acquire after getting the Python certificate. What is Python? Python is a high-level, object-oriented, dynamic, interpreted, and multipurpose programming language i.e multi-paradigm language. Python's syntax, dynamic typing, and interpreted nature make it an excellent scripting language. It supports a variety of programming paradigms, including object-oriented, functional, and procedural styles. Additionally, because it is an, it cannot be converted to computer-readable code before running at runtime. Python is used for task automation. Use of ... Read More
In Java, Array is an object. It is a non-primitive data type which stores values of similar data type. As per the problem statement we have to find mean and median of an unsorted array in Java. Mean of an array can be derived by calculating the average value of all the elements present inside the array. Mean= (sum of all elements present in array) / (total number of elements present) Median of an array represents the middle element present in an odd number sorted array and if the sorted array consists of even number, then median can be ...

An array is a linear data structure in which elements are stored in contiguous memory locations. As per problem statement, we have to alter two array elements with each other. Altering two array elements in other words can also be called swapping or exchanging two elements with each other Let’s explore the article to see how it can be done by using Java programming language. To Show you Some Instances Instance-1 Suppose we have the below array = [10, 2, 3, -5, 99, 12, 0, -1] Now if we swap the 5th and 8th elements, Then, we have the new ... Read More
Artificial Intelligence (AI) has been a hot topic for some time now & for good reason. AI has the potential to revolutionize many aspects of our everyday lives, from healthcare to education to transportation. The rise of artificial intelligence (AI), which has replaced all previous technologies, is being seen around the world. And one of the key technologies powering AI is Java. Exploring the Power of Java for AI Development Java is a popular programming language that was first released in 1995. It is known for its versatility & ease of use, which makes Java a great choice for AI ... Read More
An array is a linear data structure in which elements are stored in contiguous memory locations. As per the problem statement, finding number elements smaller than a given number means we need to compare and count only the smaller elements in the array. Let’s explore the article to see how it can be done by using Java programming language. To show you some instances Instance-1 Suppose we have the below array [10, 2, 3, -5, 99, 12, 0, -1] and the number is 9 Now the number of elements that are smaller than 9 are [2, 3, -5, 0, -1] ...

In Java, Array is an object. It is a non-primitive data type which stores values of similar data type. As per the problem statement we have given a sub array and a number and we have to find how many elements in this sub array are greater than that given number. So, we have to compare every element of the array with the given number and print the element if anyone is greater. Let’s explore the article to see how it can be done by using Java programming language. To Show you Some Instances Instance-1 Given Array= [12, 23, 34, ... Read More
Introduction When building web pages using Bootstrap, it may be useful to add an image before the label of an optgroup element. This can help to visually group options within a select element and make the page more user-friendly. In this article, we will discuss adding an image before the label of an optgroup element using Bootstrap. What is an optgroup? An optgroup is an HTML element that groups related options within a select element. The optgroup element creates a label for the group of options, and the options within the optgroup are indented and visually grouped together. Syntax ... Read More
