Python's key data structures are lists and tuples. Once elements of tuples are set they cannot be changed. This is called immutability. But list elements can be modified after initialization. When dealing with data that needs to be grouped together, a for loop is used to create tuple lists. Lists are more adaptable than tuples due to their ability to be modified. This tutorial demonstrates creating a list of tuples using a for loop, simplifying repetitive tasks. Syntax for variable in iterable: # loop code Basic Operations on Tuples Example # Initializing my_tuple = ... Read More
This walkthrough is all about creating a dictionary of tuples in Python. This data structure stores key-value pairs. By combining dictionaries and tuples, a dictionary of tuples can be created. The benefit is organized and accessible data in a structured format. Becomes easy to represent multiple values for each key, such as student grades or contact information. Let us see how this efficiently stores and retrieves complex data. Syntax Ensure Python is installed on your system for its simplicity and readability. Create a dictionary of tuples using the following syntax: dictionary_name = {key1: (value1_1, value1_2, ...), key2: ... Read More
ASCII, stands for American Standard Code for Information Interchange which is a method used for encoding characters by assigning them to a specific numerical value. The numerical values thus assigned are known as ASCII codes and are extensively utilized in computer systems to represent various characters including letters, numbers, punctuation marks, and special control characters. Example 1: Using charCodeAt() The following code illustrates a program to receive input character from the user using the ‘charCodeAt()’ function and then display the corresponding ASCII code for that character. Syntax string.charCodeAt(index) Algorithm Step 1 :Start with declaring the HTML tag. Step ... Read More

To write javascript advanced code you can run across instances where you need to convert a DOM (Document Object Model) NodeList to a more adaptable data structure like an array. Although nodelist is just like an array in any programming language. However, it does not contain fever characteristics than an array. You can use Javascript to convert a nodelist into an array to work more appropriately. Example 1 This example provides code to convert a nodelist into an array using javascript. The code uses the nodeListToArray function to perform the conversion. Algorithm Step 1 :Create an array ... Read More

This tutorial is all about string slicing. This involves creating a new string using the first and last two characters of a given string. Examples include using string slicing to extract the first two characters of a string. Such as "he" and "lo, " and combining these slices to create a new string with the first and last two characters. String manipulation methods prove handy while working with large strings or performing specific operations on a string's individual components. Let us explore several ways to handle this. Algorithm Begin with the string that has ... Read More
In Python, lists are a versatile data structure that allows you to store and manipulate collections of items. There may be use cases where you need to remove specific elements from a list based on certain criteria. In this tutorial, we will learn how to remove odd elements from a list in Python. Using a For Loop and remove() method The approach is to use a for loop to iterate through each element of the list and check if the element is odd or even and then use the remove() method to remove it from the list. Syntax remove() remove(item) ... Read More
In Python, fetching characters with odd frequencies from a given string can be a very common task in text processing and data analysis. In this article, we will learn various methods to fetch the odd frequency characters of a string in Python. Using a Dictionary Dictionaries are very convenient when there is a need to keep track of the frequencies of elements Approach To get the odd frequency elements, We will iterate through the entire string, and for each character in the string, we will increment the character count in the dictionary. At the end of the iteration, we will ... Read More
