Creating and Inspecting Series and DataFrames

Now that you've met Pandas, it's time to build with it.

In this lesson, you’ll create actual Series and DataFrames from Python lists and dictionaries. These objects let you store, label, and organize your data in powerful ways — and Pandas makes it easy.

Let’s jump in and explore by doing.

복사
import pandas as pd

# Create a Series of daily step counts
steps = pd.Series([8000, 9200, 10200], name="Steps")

# Create a DataFrame of sales records
sales = pd.DataFrame({
    "Product": ["Book", "Pen", "Notebook"],
    "Price": [12.99, 1.50, 4.75]
})

print("Steps Series:\n", steps)
print("\nSales DataFrame:\n", sales)

You’ll also learn how to:

• Use .head() to preview your data
• Use .info() to check structure and memory
• Use .describe() for quick stats like mean and count

Try them all — they’re your data inspection tools!

Watch the slide deck to get a visual feel for how Series and DataFrames behave in different scenarios.

In the next lesson, we’ll learn how to select and access specific data from these objects.
