How to make div elements display inline using CSS?
To make div elements display inline using CSS, is a very simple and easy process. There are various approaches which we can use to make div elements display inline. In this article we will be understanding five different approaches and some other properties to make div element display inline. We are having three div boxes which are block element, our task is to make div elements display inline using CSS. Approaches to Make div Elements Display Inline Using CSS Here is a list of approaches to make div elements display inline using CSS which we will be discussing in this ...
Read MoreProtected variable in Python
In programming the concept of protected variable is used to create an access control system. In this system, we establish a hierarchy or level of access control. This concept solidifies the basis of object-oriented programming. The technical meaning of a protected variable remains the same but the syntax and behaviour may vary between different programming languages. Python follows the conventional logic of accessing and manipulating the attributes and methods, but the representation and degree of enforcement of access control is a little different. Understanding Protected Variables in Python Protected variables in python manages the internal use of the attributes and ...
Read MorePython Program to Extract Strings between HTML Tags
HTML tags are used to design the skeleton of websites. We pass information and upload content in the form of strings enclosed within the tags. The strings between the HTML tags determines how the element will be displayed and interpreted by the browser. Therefore, the extraction of these strings plays a crucial role in data manipulation and processing. We can analyse and understand the structure of the HTML document. These strings reveal the hidden pattern and logic behind the construction of a webpage. In this article, we will be dealing with these strings. Our task is to extract the ...
Read MorePython Program to Extract String Till First Non-Alphanumeric Character
Python strings are sequence of characters that represent information or data. A normal string can contain various characters that are enclosed within single or double quotes but an Alphanumeric string only consist of digits and letters. Both alphanumeric and non-alphanumeric strings are used and applied in various scenarios including password protection, data processing and validation, formatting etc. Specific patterns can be identified and extracted. We can also provide different combinations using these types of strings. We will perform an operation based on these strings. Our task is to extract a string till first non-Alphanumeric character is encountered. Understanding the ...
Read MorePython program to extract N largest dictionaries keys
A python dictionary is a data structure that can be used for numerous operations making it a prolific programming tool. It stores data in the form of key-value pairs i.e., each data can be labelled with a unique key. Keys in dictionaries are identifiers that are associated with different values, these values can be accessed, modified and deleted. Based on the task, keys can be sorted and extracted in different orders. In this article, we will be discussing a similar concept of extracting N largest dictionaries keys. We will operate on these unique keys and extract the relevant data. ...
Read MorePython Program to Extract Mesh Matching Strings
Pattern recognition is an important programming concept. It allows us to retrieve specific data that satisfies a particular condition or match a particular sequence. This principle is helpful in various fields including language and image processing. String matching helps us to extract meaningful information from a large collection of data. In this article, we will be discussing a similar concept of extracting mesh matching strings from a given list of strings. Mesh matching focuses on the extraction “similar” strings of equal length, let’s discuss this problem in detail. Understanding the Problem The main concept is to extract similar ...
Read MorePython program to extract key-value pairs with substring in a dictionary
Dictionaries in python are data structures that store data in the form of key-value pairs. Each key is unique and it is associated with different values. A dictionary helps us to access and retrieve data efficiently allowing a programmer to build an optimized code. Specific key-value pairs can be extracted from a given dictionary based on different requirements. This selective item extraction helps us to produce a dictionary consisting of relevant information. In this article, we will be discussing a similar concept of item extraction from a dictionary based on a reference “substring”. Understanding the Problem We ...
Read MorePython program to extract dictionary items for custom values
Custom values are specific values that are defined and selected under certain criteria. In a large and complex dataset, specification is very important for constructing an optimized program and therefore extraction of relevant data becomes very important. We can pass a reference list according to which the values can be extracted. This reference list has its own implications as it stores concise information. In this article we will be discussing a similar concept of extracting dictionary items (both keys and values) for a custom data passed through a list. Understanding the Problem We will create a dictionary consisting ...
Read MorePython program to extract a single value from JSON response
Value extraction is a very popular programming concept and it is used in a wide variety of operations. However extracting values from a JSON response is a different concept all together. It helps us to build logic and target specific values in a complex dataset. This article will explain the various methods that can be used to extract a single value from a JSON response. Before we start with value extraction, let’s focus on understanding the meaning of a JSON response. What is a JSON Response? A JSON (JavaScript Object Notation) response is a widely accepted data format through ...
Read MorePython program to equal character frequencies
Python consists of numerous built-in functions that are designed to perform a wide range of operations including string manipulation, array analysis, algebraic reasoning etc. Strings in python is a data type in which characters are arranged in a sequence. These characters are indexed to acquire specific position in a sequence, we can initiate basic string operations with the help of these index values. This article will elaborate on a similar string-based operation where we will modify an input string to equalize the character frequency. Understanding the Problem Our task is to modify a string in a manner that each ...
