Can someone tell me what is the most used things in python and what should a python beginner focus on????!!!!

Answer 1

As a beginner, focus on learning the basic building blocks of the language. How to do simple calculations. To do interaction with the user of the program, by taking input and printing output. Using loops and conditions. Working with strings, and with lists. Writing functions. Using error handling.

Just one step at a time. You will use all these things and more, when building programs. There is no single superior feature that's more important than others. Following the lessons on Sololearn is a good start.
