Table Structure

Typically one of the first things we do upon importing a new dataset is to inspect its structure.

In this section, we cover inspecting the structure of a table. The section is organized as follows:

  1. Dataset Summary where we look at how to obtain an overall summary of the structure of a table including its dimensions, size, column names, and data types.
  2. Dimensions where we cover how to get the number of rows and number of columns in a table.
  3. Column Names where we cover how to get the names of the columns of a table.
  4. Data Types where we cover how to get the data types of the columns of a table.
  5. Memory Use where we cover how to get the size of a table or a column of a table.
