What are Namespace Packages? Namespace packages are a type of package in Python that allows you to split the sub-packages and modules within a single package across multiple, separate distribution packages. Unlike normal packages, the namespace packages don't require _init_.py file. Automatically importing all submodules within a namespace package serves several purposes, like auto-registration without manually importing, and to load all available plugins in a system. This article discusses the two methods that you can use to import all the sub-modules of a Python namespace package - Using pkgutil.iter_modules() Using ... Read More
In Python, strings and bytes are two different types of data, Where the strings are the sequences of unicode characters used for text representation, While bytes are sequences of bytes used for binary data. Converting strings to bytes is used when we want to work with the raw binary data or perform low-level operations. This can be done by using the built-in encode method. Using Python encode() Method The Python encode() Method is used to convert the string into bytes object using the specified encoding format. Syntax Following is the syntax for Python encode() method ... Read More
While working with the strings, Checking if the string exists inside another string is a common task and can be achieved by using the in keyword. But, In this article we are going to see how to check if multiple strings exist in another string in Python. For example, checking the multiple strings: "TP", "WELCOME", exists in the string "WELCOME to TP". For achieving this, Python provides different methods including loops, any() and all(). Using Python any() Function The Python any() function returns true if any of the element of the given iterable (such as list, ... Read More
The strings are the fundamental data types that are used to store text. When working with the string, Checking if the string is empty or not is a common task. An empty string is nothing but the string with zero characters. There are various to check if a sting is empty, But choosing the elegant ways helps to improve the code readability. Let's dive into the article to learn more about it. Using if not my_string In Python, empty strings are considered as falsy, Which evaluates to false in a boolean content. So using not my_string returns true ... Read More
The Lists in Python are used to store collections of items such as numbers, strings. While working with the list of strings, it is common to find a empty strings in the list. An empty string is nothing but a string value with zero length. Officially they are present as elements in the list, but does not hold any data and interfere in the operations like sorting, filtering. So, removing the empty strings is essential to ensure the list contains only valid values. For achieving this, Python provides the several ways. Let's dive into the article to learn ... Read More
The escape sequences are the special characters that are used to represent the whitespace characters, quotes, backslashes or non-printable characters within the string. These sequences start with the backslash followed by the character, For example result in newline. However, in some cases we will come across the situations to process or even to ignore these situations. In this article we will learn how to process the escape sequences. Example Let's look at the following example, where we are going to consider the basic approach to process the escape sequences. str1 = "Hello\tEveryoneWelcome to TutorialsPoint" print(str1) ...

Python regular expressions (regex) provide various ways to handle whitespaces, including spaces, tabs, and newline characters, which can be effectively stripped from strings using regex. This article will explain how to split a string on newline characters using different regular expressions, following are the various methods to achieve the present task. Using re.split(r"[]", text) Splitting on One or More Newlines Using Quantifier [+] Splitting on Newlines with Whitespace Using re.split(r"\s*", text) Using re.split(r"[]", text) The re.split() function splits a string wherever the specified regular expression pattern ...

If you’ve been coding in Java for some time, you might have wondered why you can't make an enum extend another class. It seems like it should, but Java won't let you. Let's break down why this happens Enumeration in Java Enumeration (enum) in Java is a user-defined datatype which stores a set of constant values. You can use enumerations to store fixed values such as days in a week, months in a year, and seasons, etc. If we had to store all seven days of a week into one single variable then we might tend to use data ...

In this problem, we are given an array of integers that may contain both positive and negative integers. We have to calculate the maximum sum of any contiguous subarray of the given array. In this article, we are going to learn how we can find the maximum subarray sum using the Kadane Algorithm using C#. Here is an example to find maximum sum in subarray: Example Input: arr = [1, -2, 3, 4, -1, 2, 1, -5, 4] Maximum Sum Subarray: [3, 4, -1, 2, 1] Sum = 3 + 4 + (-1) + 2 + 1 = 9 ... Read More
A string is a sequence of characters that can include alphabets, numbers, and symbols together or separately. In this article, we are going to learn how we can remove vowels from a given string in JavaScript using different approaches. There are a total of five vowels in the English alphabet. The five vowels in the English alphabet are: a, e, i, o, u, and they can be both uppercase or lowercase. Vowels are some specific alphabetic characters that represent specific speech sounds.There are a total of 5 vowels in 26 letters of the alphabet from A to Z, both ... Read More
