Hello would like to ask you a question, I am in the process of self-study R and Python, hope to learn some very basic things, for example, for example if you want to print out the results of a dataset, don't have to use the print this functionality, at the start and end a code directly add parentheses can, so similar to this very basic rules generally learn is definitely see much have to do is to remember, but I want to understand why, is that the language is how to design, I think about this later after learning any other language will understand better more deeply, but I don't know that what kind of other knowledge, also don't know what to learn, is development still?
