Data frame

As explained in Advanced Algorithms and Data Structures

A DataFrame is a two-dimensional labeled tabular data structure whose columns can have different types.

A DataFrame is Pandas’ internal representation for data read from a CSV file. Treat it as a SQL table with additional analytical flexibility. section 2.10.2

A practical DataFrame workflow can:

  • Partition records by test case, such as image versus text. section 2.10.2
  • Group records by method and process each method separately. section 2.10.2
  • Display results grouped by branching factor for performance comparison. section 2.10.2

How Advanced Algorithms and Data Structures covers it

How deep it goes
Explains the table-like role and grouping workflow, but does not detail DataFrame implementation internals.
Examples
Uses Huffman encoding statistics grouped by test case, method, and branching factor.
What you can do after
Apply it via Pandas to transform CSV statistics, partition and group records, and prepare comparative results.
How it connects
Connects DataFrames with Pandas, CSV files, SQL tables, data partitioning, grouping, and boxplots.
