Understanding Customer Retention Rates with Cohort Analysis using Python and Seaborn

Important note: This was created as part of my own personal learning process for data science in python. I find it extremely helpful when i write this down to help me learn better and faster. This was part of the course on DataCamp and the code is based on the course and other online resources I used. Please visit DataCamp for the original syllabus. I am currently no affiliated with DataCamp in any form and only use their resources as a learner.
