Parts of a DataFrame

To better understand DataFrame objects, it's useful to know that they consist of three components, stored as attributes:

  • .values: A two-dimensional NumPy array of values.
  • .columns: An index of columns: the column names.
  • .index: An index for the rows: either row numbers or row names.

You can usually think of indexes as a list of strings or numbers, though the pandas Index data type allows for more sophisticated options. (These will be covered later in the course.)

homelessness is available.

Instructions

100 XP
  • Import pandas using the alias pd.
  • Print a 2D NumPy array of the values in homelessness.
  • Print the column names of homelessness.
  • Print the index of homelessness.
