### Convert XML to JSON in python

XML (Extensible Markup Language) can create elements to store data. It is used for exchanging structured data over APIs and applications. JSON (JavaScript Object Notation) is also a very commonly used data structure notation to transfer the data between APIs and web applications. It is based on arrays and dictionaries. It was built as an […]

### Initialize matrix in python

A Matrix is a data structure, which is two-dimensional or more and stocks the numbers in a row and column format, much like a table. An in-built type for matrices is not available in Python but matrices can be created by making a list of lists and treating it as a matrix. This tutorial demonstrates […]

### Convert list to matrix in Python

Python provides some in-built data types to stock multiple items in a single variable. A List is one among these built-in data types. However, performing mathematical functions on lists is impossible due to which we need to convert the given lists to matrices or arrays in order to allow the successful performance of certain mathematical […]

### Convert image to grayscale in python

A grayscale image is an image that simply contains only the shades of gray and no other color. The main advantage of using a grayscale image over a colored image is that it brings down the computational requirements, increases the speed of processing, and makes a significant impact on the complexity of the algorithm. This […]

### Rotate image in Python

Python supports the use of images and sometimes a given image needs to be rotated to a certain angle. The image in Python is rotated about the center and with a certain angle that is specified. Image Rotation is a geometric transformation, and this process can be carried out by Inverse or Forward Transformation. This […]
