Anatomy of a DataFrame
A DataFrame in pandas is more than just a table — it's a rich data structure made up of three main parts:
The 3 Core Components
Part | Description | How to Access |
---|---|---|
Index | Labels for each row (can be numbers or names) | df.index |
Columns | Names of each data field | df.columns |
Values | The actual data inside the table | df.values |
These parts help pandas understand how to organize and reference data quickly.
Why It Matters
Understanding the anatomy of a DataFrame helps you:
- Access and manipulate data accurately
- Rename, reorder, or restructure rows and columns
- Debug issues in your analysis
If you're slicing data or joining tables, knowing how the index and columns behave is essential.
What You’ll Try in Code
In the next Jupyter notebook, you'll:
- Create a simple DataFrame
- Inspect its index, columns, and values
- See how each part stores data internally
This foundational knowledge will support everything you do with pandas later.
