Introduction
The first step in data science always involves getting a hold of data, since it's a little difficult to do data science without data. The canonical data operations package in Python is pandas, but before we can even get to that, we need to learn some other basic input/output (I/O) functions and methods in base Python. In this chapter, we'll cover the following topics:
- How to load data from common text files with built-in Python functions
- How to use the built-in
sqlite3module to save and load data - How to use basic SQL commands
- How to use the SQLAlchemy package in Python
Let's get started by using base Python to load plain text files.
