(Python Example for Beginners) Write a NumPy program to evaluate Einstein’s summation convention of two given multidimensional arrays. Note: In mathematics, especially in applications of linear algebra to physics, the Einstein notation or Einstein summation convention is a notational convention that implies summation over a set of indexed terms in a formula, thus achieving …
