Problem 1: Build a Simple Multi-Cell Notebook

Since Jupyter Notebook is an interactive environment rather than a library with functions to call, these exercises describe short notebook-building tasks meant to be carried out cell-by-cell in an actual Jupyter environment.

Problem Description

Create a notebook with: a Markdown cell titled "My First Analysis", a code cell that creates a small Pandas DataFrame, and a separate code cell that prints its .describe() summary — confirming the DataFrame persists across cells.

Input

None (structure the notebook as described).

Output

A working notebook demonstrating the Markdown heading, DataFrame creation, and reuse across cells.

Constraints

• Use at least 3 cells total (1 Markdown, 2 code).

Example Input

text
(No external input needed)

Example Output

text
(A notebook rendering a heading, a DataFrame preview, and its summary statistics in separate cells)

Concepts Covered

Markdown cells, code cells, persistent kernel state.
