Series vs DataFrame

Core Structures

Learn

Pandas mainly works with two important structures: Series and DataFrame. A Series represents a single labeled column of data, while a DataFrame represents a complete table containing rows and multiple columns.

Interactive Activity

You have one column containing customer ages. Which Pandas structure naturally represents that single labeled column?

Hint: Think about one labeled column rather than a complete table.

Analyst Workflow

Understand the structure before analyzing

A Pandas analyst should first understand the business question and the structure of the dataset before selecting data or performing calculations.

Step 1

Question

Understand what the business needs to know.

Step 2

Structure

Understand rows, columns, values and indexes.

Step 3

Select

Choose fields relevant to the question.

Step 4

Analyze

Use Pandas operations to investigate the data.

Series and DataFrames in Pandas

Pandas Series and DataFrames are fundamental data structures used in Python data analytics. A Series stores one-dimensional labeled data, while a DataFrame organizes data into rows and columns.

Understanding the difference between a Series and DataFrame is important before learning filtering, sorting, grouping, missing-data handling, and other Pandas techniques.

In practical data analysis, columns usually represent variables and rows commonly represent records or observations. This structure allows an analyst to connect a business question with the relevant fields in a dataset.

In the next lesson, you will learn how to create DataFrames using Python and Pandas.
