You are someone who want to master Python by learning all its important concepts? Or are you someone who is going for an interview and want to know which concepts to revise?
If you are either of the mentioned, then keep on reading the blog to get the checklist of python concepts.

Python is a versatile, easy-to-understand and widely used programming language. Many companies are hiring people with Python related skills. So, it is important for you to learn the essentials of it.
Many concepts are more important and essential for you understand than others. As we go through the blog, I will mark them with * (star) to let you know their importance.
*** – You must know about it along with application
** – You should know about the concept
* – You can read about it if you are interested
