How to Use Python NumPy Array – Linux Hint
Many libraries exist in Python to perform different types of tasks. NumPy is one of them. The full form of NumPy is Numerical Python, and it is mainly used for scientific computing. Multi-dimensional array objects can be defined by using this library that is called the Python NumPy array. Different types of functions exist in the NumPy library to create the array. NumPy array can be generated from the python list of numeric data, range of data, and random data. How NumPy array can be created and used to do different operations types have shown in this tutorial.

How to Use Python NumPy arange() Function – Linux Hint
Many functions exist in the Python NumPy library to perform different types of numerical and scientific operations. Creating different types of arrays for various purposes is one of the practical uses of the NumPy library. Python has a built-in function named arange() to create a list of sequential numbers. arange() is one of the array creation functions of the NumPy library to create an array of numeric ranges. The uses of the NumPy arange() function have explained in this tutorial.

How to Use Python NumPy reshape() Function – Linux Hint
NumPy library has many functions to work with the multi-dimensional array. reshape () function is one of them that is used to change the shape of any existing array without changing the data. The shape defines the total number of elements in each dimension. The array’s dimension can be added or removed, and the number of elements in each dimension can be modified by using the reshape() function. The one-dimensional array can be converted into a multi-dimensional array, but the multi-dimensional array can’t be converted into a one-dimensional array by this function. How to reshape() function works and its uses are explained in this tutorial.

How to Use Python NumPy zeros() and ones() Functions – Linux Hint
NumPy library is one of the useful libraries of python that can be used to create arrays. zeros() and ones() are the NumPy library functions to create two different arrays. zeros() function is used to create an array based on the particular shape and type. All array elements are initialized to 0, which is created by the zeros() function. ones() function works like the zeros() function. But the elements of the array created by the ones() function are initialized to 1. The uses of both functions have shown in this tutorial by using multiple examples.

How to convert Python NumPy array to python list – Linux Hint
Array object is used to store multiple values, and the list object is used in Python to do a similar task to an array object. NumPy array object is used to do different types of numerical operations in Python. The multi-dimensional array can be created by using this library. NumPy library has a built-in tolist() function to convert the NumPy array to the python list. This function does not take any argument and returns the python list. If the array is one-dimensional, then the function will return a simple python list. If the array is multi-dimensional, then the array will return the nested python list. If the array’s dimension is 0, then the function will return a python scalar variable instead of a list. How tolist() function can convert different types of NumPy array to python list is shown in this tutorial.

How to install NumPy python development environment on Ubuntu – Linux Hint
Python is a modern programming language now for supporting a large number of libraries. Various types of tasks can be done by using these libraries. NumPy is one of the useful libraries of Python to perform scientific operations. This library can be used to create a multi-dimensional array of objects. Different types of mathematical tasks can be done quickly using this library, such as sorting the array, reshaping array, statistical operation, arithmetical operations, etc. It works faster because it is developed by using the C programming language.

Python Unittest Tutorial
Unit testing is a testing method used in software engineering for individual units of any code. Users can put the individual tests to determine the status of the source and how much the code is suitable to be used. This way users can test the code quality.
Testing is done once the process of development is complete. Users can also begin testing when the test script is to be verified based on the criteria of the testing. Developers are expected to write the manual types of the source code. Generally, manually writing unit testing codes is a hectic task but in Python, it is done using an in-built function called unittest.

Samsung, Red Hat to Work on Linux Drivers for Future TechThe metaverse is expected to uproot system design as we know it, and Samsung is one of many hardware vendors re-imagining data center infrastructure in preparation for a parallel 3D world. Samsung is working on new memory technologies that provide faster bandwidth inside hardware for data to travel between CPUs, storage and other computing resources. The company also announced it was partnering with Red Hat to ensure these technologies have Linux compatibility. |
