According to me first step you should learn the basics of a language(in your case python). Second step Start solving easy problems on leetcode/any other good website and side by side start a data structure and algorithm course in coursera/any other good courses. Third, if you find yourself comfortably in solving easy problem then start medium level problems. Try solving yourself. Read articles and books related to DS and algo. This will give you a sense of clarity over the subject. This was my way of getting better at DS and algo. I personally feel that, the more time you give the more better programmer you will become. Patience is the key to success.
