62 What Is a CSV File? Read, Parse, and Manipulate CSV Data in Python (Basics to Pandas) PYTH 13.01

In this lesson, we break down what a CSV (Comma-Separated Values) file really is and how it works behind the scenes — from a simple text file on the command line to a spreadsheet in Google Sheets and a formatted table on GitHub. You’ll learn how to: Open and read CSV files using Python’s built-in open() function Use context managers (with) to safely handle files in real projects Read lines, strip newline characters, and split values by commas Extract headers, rows, and individual columns Slice and manipulate string data for clean, structured output Understand when and why to move from manual parsing to pandas This lesson focuses on core CS fundamentals: files, lists, strings, indexing, and data manipulation — the same concepts you’ll use in first-year computer science courses and real-world industry applications. If you want a production-ready approach, we also introduce how pandas simplifies CSV handling with read_csv() and DataFrames. 📌 Join our 100% free course for full lessons, slides, source code, and real project examples: 👉 https://industry-python.thinkific.com
