It provides a range of storage choices for various data kinds and situations, including files, queues, tables, and blobs. Azure Portal, Azure Storage Explorer, Azure PowerShell, Azure CLI, and the Azure Storage REST API are some of the ways users can access Azure Storage.What is Blob Storage?Blob Storage is a kind of object-based cloud storage intended for unstructured or semi-structured data. Blobs can be accessed by client libraries, REST APIs, or Azure PowerShell and CLI. They are arranged into containers, which resemble ... Read More
In Python, the file.readlines() method is a convenient way to read multiple lines from a file into a list. Each line from the file becomes an element in the list. It reads all the lines from a file and stores them in a list, which can be easily manipulated in your code. Basic Usage of file.readlines() Function The simplest way to use a file.readlines() is by opening a file, calling the method, and printing the results. Example The following example code reads all lines from sample.txt into a list and prints each line without extra whitespace. # Open the ... Read More
In Python, the encoding() and decoding() refer to the processes of converting data between different formats, particularly when dealing with strings and bytes. Both processes are essential for ensuring data is correctly formatted for storage and transmission, especially when working with different languages or systems that may interpret data differently. Encoding in Python Encoding is the process of converting a string (text) into a byte sequence. This is often necessary when you need to store or transmit data as binary. When you want to save text to a file in a certain character encoding (e.g., UTF-8, ASCII) or send text ... Read More
When working with JavaScript inside HTML documents, developers may come across the CDATA section. It can be helpful when dealing with older XHTML documents or embedded JavaScript in XML-based markup. What is a CDATA Section? A CDATA (Character Data) section is a special syntax used in XML and XHTML documents to prevent certain characters from being interpreted as markup. It ensures that special characters like < and & are treated as plain text rather than triggering parsing errors. Syntax − Why Was CDATA Used tag? To avoid parsing the symbols &, it is added in …. It ... Read More
In this article, we will learn to pass a lambda expression as a method argument in Java. A lambda expression is a short block of code that takes in parameters and returns a value. Lambda Expression Lambda expressions allow passing functionality as a method parameter, reducing the need for anonymous classes. They are often used in functional interfaces, especially when working with collections and streams. Problem Statement Given an Arraylist the goal is to reverse the strings present in it. Below is a demonstration of the same − Input ("Apple", "Orange", "Grapes") Output elppA, egnarO, separG Reversing Strings in ... Read More
In this article, we will learn about the !! (not not) operator in JavaScript.This double negation forces a value to be evaluated as either true or false. What is the !! Operator? The double negation(!! ) operator is the! Operator twice and calculates the truth value of a value. It returns a Boolean value, which depends on the truthiness of the expression. How It Works: The first ! negates the value, converting it to true or false. The second ! negates it again, effectively converting it into a strict boolean (true or ... Read More
In this article, we will learn about JavaScript's closures and anonymous functions. JavaScript is a powerful language that allows developers to write expressive and concise code. Two concepts that often confuse beginners are closures and anonymous functions. While they share some similarities, they serve different purposes and function differently in JavaScript What is Anonymous Functions? An anonymous function is simply a function without a name. Anonymous, as the name suggests, allows the creation of a function without any name identifier. It can be used as an argument to other functions, assigned to a variable, or immediately invoked. They are called using ... Read More
In this article, we will learn the ResultSetMetaData getColumnLabel() method in Java. When working with databases in Java, the ResultSetMetaData interface provides valuable information about the structure of a ResultSet, such as column names, types, and properties. What is getColumnLabel()? The getColumnLabel() method of the ResultSetMetaData (interface) retrieves the display name of a particular column. This method accepts an integer value representing the index of the column in the current ResultSet object, as an argument. Syntax − String columnLabel = resultSetMetaData.getColumnLabel(); Parameters: The index of the column (starting from 1). Returns: A ... Read More
In Python, you can open a file for both reading and writing using the built-in open() function. This is essential when you want to manipulate a file's content without needing to close and reopen it repeatedly. This mode allows us to read from and write to the file simultaneously, but it will raise an error if the file does not exist. We can also use Write and Read (w+) mode, which will truncate the file. Opening a File in Read and Write Mode To open a file for reading and writing, you can use the Read and Write Mode ('r+'). ... Read More
