 Data science, at its heart, is a computer programming exercise. Data scientists use computers to store, transform, visualize, and model their data. Each computer program will expect your data to be organized in a predetermined way, which may vary from program to program. To be an effective data scientist, you will need to be able to reorganize your data to match the format required by your program.
