Lesson refers to data types from R

[maneesha]

The Starting With Data lesson refers to data types like characters and factors which are not in Python. I'm guessing this is a carryover from the R lessons.

A DataFrame is a 2-dimensional data structure that can store data of different types (including characters, integers, floating point values, factors and more) in columns. It is similar to a spreadsheet or an SQL table or the data.frame in R. A DataFrame always has an index (0-based). An index refers to the position of an element in the data structure.
