Selecting DataFrame rows

The most explicit and preferred way to select DataFrame rows is with .iloc and .loc. They are both capable of selecting by rows or by rows and columns.

This recipe shows you how to select rows from a DataFrame using the .iloc and .loc indexers:

  1. Read in the college dataset, and set the index as the institution name:
    >>> college = pd.read_csv(
    ...     "data/college.csv", index_col="INSTNM"
    ... )
    >>> college.sample(5, random_state=42)
                         CITY STABBR  ...  MD_EARN_WNE_P10  GRAD_DEBT_MDN_SUPP
