How deeply does Data Without Labels cover data frame?

Demonstrates construction, loading, inspection, column transformation, merging, and duplicate removal without explaining dataframe internals.

Data frame

As explained in Data Without Labels

A dataframe is a two-dimensional tabular data structure whose rows represent observations and whose columns represent labeled variables that may have different types.

A data frame is a two-dimensional table for organizing observations in rows and labeled variables in columns. Columns can contain different kinds of values, making the structure useful for combining scraped, survey, or transactional data before analysis. section 7.15 section 11.5

A practical data-frame workflow includes:

Remove duplicate rows only after distinguishing repeated real-world events from repeated recordings of one event. section 11.5

Customer-review analysis

A review data frame stores scraped review fields, is saved to CSV, and is loaded for inspection. Text transformations operate on its body column; sentiment results are classified, plotted, and merged back into the review data. section 7.15
