A Numpy array is an N-dimensional array also called a ndarray, it is a main object of the NumPy library. In the same way, the pandas series is a one-dimensional data structure of the pandas library. Both pandas and NumPy are validly used open-source libraries in python. Below we can see the one-dimensional numpy array. NumPy array array([1, 2, 3, 4]) The pandas Series is a one-dimensional data structure with labeled indices and it is very similar to a one-dimensional NumPy array. Pandas Series: 0 1 1 2 2 3 ...

Both pandas and NumPy are validly used open-source libraries in python. Numpy stands for Numerical Python. This is the core library for scientific computing. A Numpy array is a powerful N-dimensional array object which is in the form of rows and columns. NumPy array array([[1, 2], [3, 4]]) Pandas provide high-performance data manipulation and analysis tools in Python, it allows us to work with tabular data like spreadsheets, CSV, and SQL data. And it has data structures like DataFrame and Series that are mainly used for analyzing the data. DataFrame is a 2-dimensional labeled data structure used to ... Read More

In this tutorial, we will learn to create an empty and a full NumPy array. NumPy stands for Numerical Python. It is a Python library that performs numerical calculations. It provides a multidimensional array object. NumPy is a popular Python library used for working with arrays. It also has functions for working in the domain of linear algebra, sorting, and matrices and is optimized to work with the latest CPU architectures. NumPy is very fast as it is written in C language, making it more effective for creating arrays. An array represents a collection of items of the same data ... Read More

Finding the roots of polynomials is an essential operation in mathematics, and NumPy provides an easy and efficient way to accomplish this task. NumPy is a powerful library for scientific computing in Python, and its functions for polynomial manipulation are especially useful. Syntax The NumPy library has a function named roots() that can be used to find the roots of a polynomial. numpy.roots(p) where p is the polynomial coefficients represented as a 1D array or sequence. The function returns an array of the roots of the polynomial. Algorithm With NumPy, finding a polynomial's roots is a rather straightforward process ... Read More

What is Concatenation of Arrays? The process of combining the arrays into a single array or merging the arrays into a single array is known as Concatenation of arrays. This mechanism can be done in many ways using several techniques. Let us discuss all techniques that help in concatenation of arrays in Python. Input Output Scenarios Consider three arrays to perform concatenation. arr1 = [“ Hello ”, “ World ”, “ My ”, “ Name ”, “ is ”, “ Python ”] arr2 = [“ Hello ”, “ World ”, “ My ”, “ Name ”, “ is ”, “ ...

There are several techniques that helps us to check whether the given arrays are equal or not. The comparison of an array will not depend on the indices of the elements, it will only compare whether that particular element in one array is present in the other array or not. Let us discuss few techniques that compares two arrays and checks whether they are equal or not. There are several techniques that helps us to check whether the given arrays are equal or not. The comparison of an array will not depend on the indices of the elements, it will ... Read More

Data analysis and understanding depend heavily on data visualization. There are several libraries available for the popular programming language Python that might aid with data visualization. Data scientists regularly use meshgrid() and contourf() to produce 2D and 3D graphs because they are excellent tools for facilitating the display of complicated data sets. For building point grids for various visualizations, like heat maps and contour plots, Meshgrid() is a very useful method. We will talk about two crucial methods in this blog post: meshgrid() and contourf (). These methods are essential for two-dimensional visualization of three-dimensional data. What is Meshgrid()? Meshgrid() ... Read More

This tutorial provides a step-by-step guide on how to convert a NumPy array to a dictionary using Python. In NumPy, an array is essentially a table of elements that are typically numbers and share the same data type. It is indexed by a tuple of positive integers, and the number of dimensions of the array is referred to as its rank. The size of the array along each dimension is defined by a tuple of integers known as the shape of the array. The NumPy array class is known as ndarray, and its elements can be accessed by using square ... Read More

Introduction Two well-liked regularization methods for linear regression models are ridge and lasso regression. They help to solve the overfitting issue, which arises when a model is overly complicated and fits the training data too well, leading to worse performance on fresh data. Ridge regression reduces the size of the coefficients and prevents overfitting by introducing a penalty element to the cost function of linear regression. The squared coefficient total is directly proportional to this penalty component. Adversely, a penalty term is added in lasso regression that is proportionate to the total of the absolute values of the coefficients. This ... Read More
