In the Python dictionary, can one key hold more than one value?

Updated on 24-Mar-2023 14:09:40
What is a Dictionary in Python? A dictionary is Python’s own indigenous representation of a data structure, and can be considered similar to maps in C++. It is a dynamic data structure which stores key-value pairs dynamically, and is mutable. It can be better understood as an associative array, where each element is associated with its key value. Can one key hold more than one value? Although dictionaries in Python store values as key-value pairs, it is possible to store more than one value corresponding to the same key in a dictionary. This is performed by setting containers like ... Read More

How does a Python interpreter work?

Updated on 24-Mar-2023 13:58:32
What is an Interpreter? The Python interpreter works as a computer converter that converts high-level language to low-level machine language, which is essential for the computer to understand the code written by a programmer. Python codes are executed by an interpreter called CPython, which is written in C language and executes instructions in a block of code one line after another. Steps used Lexing Parsing Creation of byte code Conversion to machine-executable code Returning output Let’s dive into the steps in detail. Step 1: Lexing The first step of analyzing a code block in ... Read More

Implementation of Teaching Learning Based Optimization

Updated on 23-Mar-2023 16:48:21
Introduction Teaching Learning Based Optimization (TLBO) is based on the relationship between a teacher and the learners in a class. In a particular class, a teacher imparts knowledge to the students through his/her hard work. The students or learners then interact with each other among themselves and improve their knowledge. Let us explore more about Teacher Learning Based Optimization through this article. What is TLBO? Let us consider a population p (particularly a class) and the number of learners l in the class. There may be decisive variables (subjects from which learners gain knowledge) for the optimization problem. Two modes ... Read More

Image Segmentation by Clustering

Updated on 23-Mar-2023 16:33:23
Introduction Image Segmentation is the process of partitioning an image into multiple regions based on the characteristics of the pixels in the original image. Clustering is a technique to group similar entities and label them. Thus, for image segmentation using clustering, we can cluster similar pixels using a clustering algorithm and group a particular cluster pixel as a single segment. Thus, let's explore more image segmentation using clustering, Image Segmentation The process of image segmentation by clustering can be carried out using two methods. Agglomerative clustering Divisive clustering In Agglomerative clustering, we label a pixel to a close ... Read More

How to add PDF in Tkinter GUI Python?

Updated on 23-Mar-2023 15:19:45
This article will teach us how to display PDF files in the Tkinter GUI. We will be using the PyMuPDF library to read the pdf files and convert them into images which will then be displayed using Tkinter. For our task, we will do the following steps − Read the PDF file. Define a transformation matrix to apply on the pages of PDF to get their images. Count the total number of pages for error checking. Define the screen (the canvas) for our GUI. Define a helper function for converting a PDF page to a PIL image. Define ... Read More

Commands to Get Min, Max, Median, and Mean of a Dataset

Updated on 23-Mar-2023 16:33:43
When working with datasets, it's important to understand characteristics of data. One of most fundamental aspects of a dataset is its central tendency - point around which data tends to cluster. This can be quantified in a number of ways, including minimum, maximum, median, and mean. In this article, we'll explore these different measures of central tendency and show you how to calculate them using a variety of programming languages. What is Minimum of a Dataset? The minimum of a dataset is smallest value in set. This value is useful for understanding lower bounds of data and can help identify ... Read More
