Challenge 4: Altering DataFrame
Pandas provides a plethora of tools that allow for easy modification of both data and structure of DataFrames. These capabilities are essential because:
- Data Cleaning: Real-world datasets are often messy. The ability to transform and clean data ensures its readiness for analysis.
- Versatility: Frequently, the structure of a dataset may not align with the requirements of a given task. Being able to reshape data can be a lifesaver.
- Efficiency: Direct modifications to DataFrames, as opposed to creating new ones, can save memory and improve performance.
Getting familiar with the techniques to alter data and the structure of DataFrames is a key step in becoming proficient with Pandas.

. - Rename columns in a DataFrame. Change the
Name
column intoFull Name
and theAge
column intoAge (years)
. - Drop a column
City
from a DataFrame. - Sort a DataFrame based on the
Age
column (descending).
