1. Why learn basic concepts
In the study of any subject, basic concepts are the basis of learning. As in the pyramid, the core is also the bottom foundation. Studying the literal meaning and substantive thoughts of basic concepts carefully can deepen the understanding of knowledge and achieve the effect of inferences in learning, so as to systematize and network the knowledge learned. In programming learning, many basic concepts will be reused in different business scenarios and applications. For example, the command mode and editing mode in Jupyter Notebook (Python IDE) are similar to those in VIM; many magic commands in Jupyter Notebook are also commonly used commands in Linux. Therefore, we must study the basic concepts attentively so that we can go faster and faster on the road of learning.
