Each programming language has characteristics that distinguish it from other languages and make it suitable to varying degrees for each of the purposes of these languages, and programming languages also have common characteristics and limits by virtue of the fact that all these languages are designed to interact with the computer, as each language has a special design that differs from the way other languages are designed In dealing with data, they also differ in the nature of the methods and facilities provided by the language to deal with a specific problem, hence this study aims to make a comparison between two programming languages represented in C# and PYTHON through their use in the field of computational engineering by applying the Bezier algorithm to find out the differences and contrasts between the performance of the two languages through a number of evaluation criteria, which are speed, memory usage, and the number of lines (loc).
