Python R; Syntax: Python has a simple and easy-to-learn syntax that emphasizes readability and reduces the cost of program maintenance. It uses indentation to create blocks, and its syntax allows programmers to express concepts in fewer lines of code than languages like Java or C++.The main difference is that the R function is vectorized. If states = [TX, CA, NY] and numbers = [1, 2, 3] then the paste function should return ['TX1', 'CA2', 'NY3']. R's problem is simpler because python has more types to worry about: lists, numpy arrays, pandas Series, so it is not clear what the return type should be if numbers is a numpy array and states is …
