In order to learn the basics of data analysis, I started learning by selecting a package from the roadmap provided by the instructor. I started with basic knowledge of Python grammar and crawling, and then I was surprised once by the part where the loop was dealt with in depth while doing it 1.25 times, and I was surprised again by the material that solved various examples to get used to the grammar. I think this is a great lecture for those who want to get started with Python to learn grammar.
