Write a detailed tutorial on Python

We want a python expert who is good in explaining and teaching others the concepts of python. We do not want those freelancers who think writing tutorial is like reading from other websites/blogs and rewrite it. We want a new approach to explain the concepts of python. You need to write a detailed tutorial on each topic. You need to write a proper executable code in python. You need to draw nice diagrams when ever necessary. You should have more than 5 years of experience in python. You should have a prior experience in writing a tutorial. You should be flexible to understand our requirement and should be ready to write tutorial based on our feedback. You should be flexible to modify article multiple times if we find any problem in understanding the tutorial or any mistakes in the explanation. Currently there can be 150+ topics on Python. This is for an idea to understand the amount of effort and learning you will get while writing tutorial for us. Note: Remember, this tutorial writing will help you getting knowledge to explore in details about the language which will indirectly help you in your career.
