Challenge 2: Data Grouping
Pandas, known for its comprehensive data analysis tools, offers a versatile grouping mechanism called the groupby method. This method is pivotal for aggregating data based on certain criteria, a process similar to the SQL GROUP BY statement. The benefits of using groupby are manifold:
- Granularity Control: You can aggregate data at different levels of granularity, from high level (e.g., grouping by country) to fine-grained (e.g., grouping by individual timestamps).
- Simplicity: The
groupbysyntax is concise and expressive, making it easy to chain operations and achieve complex aggregations. - Extensibility: With
groupby, you can apply custom aggregation functions, not just the built-in ones, giving you the power to compute custom metrics for groups.
When diving into data exploration, the grouping capabilities of Pandas can reveal insightful patterns and trends by segmenting data into meaningful categories.

Demonstrate data grouping in Pandas with the following tasks:
- Group data by a single column
A. - Sum all data grouped for column
Ausing the built-in function. - Apply multiple aggregation functions simultaneously. Get
sumaggregation forBcolumn andmeanforCcolumn. - Group by multiple columns (
AandB).
