step 2 : Solve some basic question.

After learning all the concepts try to solve 10 or more problems based on each concept and try to analyze your code line by line. This will help you to get rectify your concept and will also boost your concept. First, try to solve small questions from the internet or any coding practice book. Solve questions without taking any help from any source. How to start solving questions? There is some concept behind every question, try to find out that concept and then think how can you solve this question like whether you have to use a list, dictionary or tuples, or strings, do you need any loop to solve? If you need a loop then which type of loop you need. What is the concept hidden behind the question to solve? Then use your learned programming concept to solve questions.
