Python Day 167: Reading CSV Files in Python
Welcome to Day 167 of The Complete Python Bootcamp.
In this session, you will explore how to read data from CSV (Comma-Separated Values) files in Python. CSV files are one of the most common formats for storing and exchanging structured data, making them an essential part of data analysis, automation and software development.
Many real-world applications rely on external data stored in CSV files. Whether you're analysing sales figures, processing customer records or importing datasets into your programs, knowing how to load and work with CSV data is a fundamental Python skill. This lesson introduces the process of reading CSV files and preparing their contents for further analysis, manipulation and visualisation.
Today, you will learn how to open CSV files, read structured data into your Python programs and begin working with information stored outside of your code.
By the end of this lesson, you will have a solid understanding of how to load CSV data and use it as the foundation for data processing, reporting and analytics projects.
