In this article, the user will understand how to encode-decode messages in python. Users can enter a message and select the desired option whether to encrypt or decode it. The encode or decoded message would be depicted on GUI window after clicking on the respective button. The Tkinter module would be used to develop interactive GUI applications. The code creates a straightforward GUI window with an input entry field, two encoding and decoding buttons, and an output label to show the outcome. Message Encode-Decode Using Python Tkinter Code Explanation and Design Steps − Step 1 − Open Jupyter Notebook ... Read More
Problematic data structures include Python lists and dictionaries, these two structures being ordered collections that allow changes, while an unordered dictionary stores values like maps. Dictionaries provide more efficient use by holding key-value pairs; unlike other data types which hold single values at a time as elements in them. In this article, merging two lists involve compiling all dictionaries from both lists into one large list, their order in this merged list will mirror how they appeared in their respective original lists, initially the order may contain only those from one original list followed by others from both original lists. ...

Programming's basic concept of pattern creation entails producing ordered sequences or patterns. Python as a powerful programming language, provides a great range of tools as well as modules that make it simple to manage patterns. The time() is one kind of module that gets tools for managing time-related tasks. The time() module, while mostly used for time monitoring and measurement, can also be creatively utilized to produce dynamic patterns that alter over time. We will examine two different methods for pattern generation using the Python time() function in this article. We will examine the underlying algorithms of each strategy, offer ... Read More
The Number Theoretic Transformation (NTT) is a key component in many computational applications in the field of number theory. It is essential in areas like encryption, signal processing, error-correcting codes, and more because it makes large-number multiplication and convolution processes efficient. The NTT is a fast method for computing polynomial multiplications modulo a prime integer and is closely connected to the Fast Fourier Transform (FFT). We will examine two different methods for implementing the Number Theoretic Transformation in Python in this article. We will look into the Cooley-Tukey algorithm, one of the most popular methods for putting the Fast Fourier ... Read More
In this article, the user will learn the percentage occurrence at the index in the list. Determining the percentage recurrence of a particular value at a given index in a list or array is a common task in data analysis or processing. This kind of computation can offer insightful information on the distribution and trends in the data. In this article, we will examine two distinct strategies for solving this problem, talk about their algorithms, give code snippets that get the desired results, and then compare the strategies. For Example − Given list : [4, 2, 3, 1, ... Read More
Peak Signal-to-Noise Ratio (PSNR) is a generally utilized statistic to compute the quality of digital signals, for images as well as video. It computes the difference between the original as well as distorted versions of the signal and gauges the amount of noise appended via compression, transmission, as well as for processing. PSNR is a utilized as tool in an assortment of applications, that has multimedia, video compression, as well as image processing. In this article, we'll monitor the two techniques for computing PSNR in Python. This method will generate algorithms, code implementations, as well as explanations that will make ... Read More
Measuring the similarity of two lists in Python is a frequent operation performed in a variety of applications. Determining the degree of similarity across lists is essential for making wise judgments and gaining insightful knowledge, whether you are working with data analysis, text processing, recommendation systems, or even social network analysis. In this article, we'll examine two distinct methods for estimating the % similarity as we delve into the subject of list similarity. Analyzing overlap or shared elements between lists is necessary to determine their degree of similarity. This metric offers a numerical assessment of the degree of similarity between ... Read More
A powerful technique for extracting data from websites, web scraping enables automated data extraction and analysis. Python offers several tools to make web scraping chores easier thanks to its robust ecosystem of modules. The libraries urllib and re (regular expressions) are two that are commonly utilized for online scraping. A Python module called urllib enables obtaining web material, processing URLs, and sending HTTP requests. It offers a simple way to connect with web servers, open URLs, and obtain HTML from web pages. On the other hand, regular expressions, which are character sequences used to construct search patterns, are supported by ... Read More
Python dictionaries constitute a flexible data structure that enables us to employ key-value pairs to store as well as manipulate data. Employing special keys, they offer a practical way to arrange and access information. Dictionaries in Python can be passed as keyword arguments to functions, which is an intriguing feature. When working with functions that require numerous inputs, this method enables greater flexibility as well as readability. By passing dictionaries as keyword arguments, we can pass a variety of arguments without having to define each one individually. Our code becomes more modular and understandable since it offers a simple and ... Read More
What is VK? VK is a Russian social media website and is more popular than Facebook in Russia. The platform is also known as VKontakte. The website is not popular outside Russia and is a mystery for European countries. VK is considered as a fierce competitor of Facebook and has the ability to beat the latter in terms of exchanging messages and adding and sharing posts. Mostly people aged between 25 and 34 are fond of the website. You can share audio, videos, and other content on this platform. Why VK alternatives? The website is not regularly updated VK ...
