Dataframes are structures used in data science that work like spreadsheet pages or database tables, allowing efficient and powerful data manipulation compared to traditional methods.
They are two-dimensional data structures with columns organized by name and data type, offering a blend of flexibility from spreadsheets and organizational clarity from databases.
Dataframes support familiar data types and allow the handling of null values, enhancing consistency by allowing specification of types for columns to prevent mismatches.
Created from various data sources, dataframes enable faster data operation, making them the preferred choice over SQL queries or traditional Excel handling.
