Data analysis is a highly iterative process involving collection, preparation (wrangling), exploratory data analysis (EDA), and drawing conclusions. During an analysis, we will frequently revisit each of these steps. The following diagram depicts a generalized workflow:
In practice, this process is heavily skewed towards the data preparation side. Surveys have found that, although data scientists enjoy the data preparation side of their job the least, it makes up 80% of their work (https://www.forbes.com/sites/gilpress/2016/03/23/data-preparation-most-time-consuming-least-enjoyable-data-science-task-survey-says/#419ce7b36f63). This data preparation step is where pandas really shines.
