List is one of mutable data structure available in python which is used to store the data of any datatype. It is denoted with the square braces "[]" and all the elements in the list are separated by comma. When we want to access an element from the list, indexing will be applied. In the same way we have the string data structure which is immutable and stores the data in the string datatype. The string is given as double quotes or single quotes. The indexing will be applied to access the elements from the string. Now in this article ... Read More

The purpose of figure aesthetics in Seaborn is to enhance data visualization by providing visually appealing and informative representations of data. Seaborn offers various figure aesthetics options that can be customized to create visually appealing plots. This aesthetics include color palettes, plot styles, gridlines, font styles, and more. Let's explore how this figure aesthetics enhance data visualization. Color Palettes Seaborn offers a wide range of color palettes that are carefully designed to be visually pleasing and provide effective differentiation between data categories. Color palettes can be applied to various plot elements, such as data points, lines, and bars. By selecting ... Read More

Arithmetic operations are the mathematical calculations on numeric data types. The following are the arithmetic operations allowed in python. Addition (+) Subtraction (-) Multiplication (*) Division (/) Floor Division (//) Modulo (%) Exponentiation (**) There are several ways to compute arithmetic operation from string. Let’s see them one by one. Using the eval() Function The eval() function in Python evaluates an expression passed as a string and returns the result. We can use this function to compute arithmetic operations from a string. Example In this approach, the eval() function evaluates the expression "2 + 3 * 4 - ... Read More

Changing the default matplotlib plot settings to Seaborn involves modifying the default plot parameters to match the style and aesthetics provided by Seaborn. This can be achieved by adjusting various elements such as the color palette, gridlines, font styles, and plot themes. Here's a step-by-step guide to changing the default matplotlib plot to a Seaborn plot in detail. Import the necessary libraries To get started, import the required libraries such as 'matplotlib.pyplot' for creating plots and 'seaborn' for applying Seaborn styles and aesthetics. The following is the code to import the libraries. import matplotlib.pyplot as plt import seaborn as sns ... Read More

Dictionary is the mutable data structure in python, which allows the user to store the data in the format of key and value. The key and value are separated by using the symbol ":". The keys are unique and the values can be repeated. The values can be given as a single element or multiple elements within a list. If we want to access the elements from a dictionary we have to use the key. It provides various functions and methods to work and manipulate the dictionaries. There are several approaches to check whether the values of a dictionary are ... Read More

Lexical order refers to the order of characters or strings based on their dictionary or alphabetical order. In lexical order, characters are arranged in the same way they would be in a dictionary. The comparison is done based on the numerical values of the characters in their respective character sets such as ASCII or Unicode. In lexical order, characters are compared based on their ASCII or Unicode values from left to right. The character with a lower ASCII or Unicode value comes before the one with a higher value. For example, in ASCII order, 'a' comes before 'b', 'b' comes ... Read More

Generally, a flashcard is a learning tool that consists of a small card or piece of paper with information printed on one side. These are commonly used to aid in memorization and learning of facts, vocabulary, definitions, equations, or any other type of information that can be presented in a question-and-answer format. With the advancement of technology, flashcards have also been adapted into digital formats, such as mobile apps and online platforms, which provide additional features like multimedia content, spaced repetition algorithms, and progress tracking. There different approaches available in python to build the flash cards, let’s go through each ... Read More

An octal number is a number expressed in the base-8 numeral system. It uses digits from 0 to 7. Octal numbers are commonly used in computer science and digital systems, especially when dealing with groups of three bits. In octal notation, each digit represents an increasing power of 8. The rightmost digit represents 8^0 (1), the next digit represents 8^1 (8), the next digit represents 8^2 (64), and so on. By combining these digits, octal numbers can represent positive integers. For example, the octal number 52 represents the decimal number as follows. (5 * 8^1) + (2 * 8^0) = ... Read More

A Dictionary is an unordered collection of data structure which stores the elements as key and value. It is mutable and in other programming languages Dictionaries are also known as associative arrays, hash maps, or hash tables. The key is the unique one and the values are of a single element or a list of elements with duplicates. A Dictionary can be created by using the curly braces {} or by using the built in function dict(). Let’s see an example of creating the dictionary in python. Example student = { 'name': 'Tutorialspoint', 'age': ... Read More
