What are Namespace Packages? Namespace packages are a special type of package that were introduced in Python 3.3. These allow you to split package contents across multiple directories. If you didn't include at least an empty _init_.py file in your package, then your package becomes a namespace package. Python supports three main types of namespace packages - Implicit namespace packages pkg_resources-style pkgutil-style Python Packages and Imports Python package is a directory containing a _init_.py file and one or more Python modules. When you import from a package, ... Read More
The modulo operator is denoted by the "%" symbol in Python. It can also be called the remainder operator because it is used to return the remainder of the division of two numeric operands. Using this operator, we can solve problems ranging from simple to complex. Syntax of Python Modulo Operator The modulo operator in Python works the same as the remainder of dividing the two numeric operands. Following is the syntax of the modulo operator - Result = a % b Where a and b are the operands, % represents the modulo operator, and ... Read More
The Boolean operators in Python return two values, either true or false. These operators are mostly used in conditional statements, loops, and logical expressions. Python has a built-in Boolean datatype that returns Boolean values based on comparisons or logical evaluations between operands. Boolean Operators in Python There are three main Boolean operators in Python: OR, AND, and NOT. These operators return Boolean values based on the operands. OR Operator in Python The OR operator in Python returns true if one of the operands is true and false if both operands are false. This operator ... Read More
The AND and & are logical operators in Python that are used to perform different operations. The AND is a logical AND operator, and the ampersand (&) is a bitwise operator. In this article, we will explore the behavior of these operators and their differences. AND Operator in Python The logical AND operator in Python needs two operands. This operator returns true if both operands are true and false if either operand is false. This operator is mostly used in situations where you want to make sure that two things are true at the same time. Example of the AND ... Read More
The OR and AND operators are the most commonly used logical operators. The logical operators are used to perform decision-making operations. These combine multiple conditions and make a decision based on them. In this article, we will understand what OR and AND operators are in Python and how they differ, along with examples for better understanding. AND Operator in Python The logical AND operator in Python needs two operands. It returns true if both operands are true, and it returns false if either of the operands is false. This operator is mostly used in situations where you ... Read More
The symbols "=" and "==" look similar but have different meanings and usability in Python. The "=" symbol is the assignment operator, and the "==" symbol represents a comparison operator. In this article, we will understand the difference between these two and how to use them. The "=" Operator The "=" operator in Python is the assignment operator. It is used to assign a value to a variable. You put the variable on the left side and the value or expression on the right side. The value on the right is stored in the variable on the ... Read More
In Python, there are various types of operators used to perform specific functions, such as (**), (^), (%), and (//). The (**) operator represents exponentiation, (^) represents bitwise XOR, (%) represents the modulus operation, and (//) represents floor division. In this article, we will understand the workings of these operators. Exponentiation Operator (**) The exponentiation operator (**) is used to raise a number to a power. This operator works the same as the Python pow() method. In exponentiation, you need two numbers: the first is the base (the number you want to raise), and the second is ... Read More
A tuple in Python is an ordered, immutable collection that stores multiple items. It supports mixed data types, allows indexing, and is commonly used for fixed data structures. What is a Two-Dimensional Table? A two-dimensional table is a way of specifying data in rows and columns, similar to a spreadsheet or a table in a Word doc. Each row represents a record, and each column represents a specific property for that record. Example The following is a two-dimensional table consisting of three rows and three columns. It is structured along two axes: vertical rows and horizontal columns, This makes the ... Read More
Data conversion between different formats is a common requirement in modern web development and data processing pipelines. Among the most frequently needed conversions is transforming CSV (Comma Separated Values) files to JSON (JavaScript Object Notation), especially when working with Node.js applications.This complete tutorial describes various proven methods for CSV to JSON conversion in Node.js with instructions on processing header rows while handling internal field commas and optimizing performance for large file sizes. Why Convert CSV to JSON? The following section provides an understanding of the reasons behind converting CSV files to JSON documents. The majority ... Read More
In programming, it is very common to work with lists, which are collections of items. But sometimes, you may want to turn a list into a single string. So in this chapter, we will show you how you can do this in Python. We will use some simple explanations and examples to make this easy, so you can understand it very well. Understanding Lists So first, we need to understand what exactly a list is in Python. So, in simple terms, we can say it is a way to store multiple values. For example, you can have a list of ...
