DataFrame is a tabular representation of data containing an ordered collection of columns, each of which can be a different type (numeric, string, boolean, and so on).
The DataFrame has both a row and column index; it can be thought of as a dict of Series all sharing the same index. In a data frame, the data is stored as one or more two-dimensional blocks rather than a list, dict, or some other collection of one-dimensional arrays.
While a DataFrame is physically two-dimensional, it can be used to represent higher dimensional data in a tabular format using hierarchical indexing
