How to Create a DataFrame from an Indexed Dictionary in Python

DataFrames are powerful structures in Python's pandas library that allow for effective data manipulation and analysis. However, when working with dictionaries, especially those that are indexed, many users may encounter difficulties in converting these structures into DataFrames. This guide will guide you through the process of creating a DataFrame from an indexed dictionary using a simple example.

The Problem

Suppose you have an indexed dictionary that stores information about students. The structure may look like this:

The Solution

To convert your indexed dictionary into a DataFrame correctly, you can use the from_dict() method available in the pandas library. This method allows you to set the orientation of the data, making it easier to structure properly.

Here's How to Do It

Import the pandas Library: Ensure you have pandas imported in your script.
