Subsetting with .loc[]

The killer feature for indexes is .loc[]: a subsetting method that accepts index values. When you pass it a single argument, it will take a subset of rows.

The code for subsetting using .loc[] can be easier to read than standard square bracket subsetting, which can make your code less burdensome to maintain.

pandas is loaded as pd. temperatures and temperatures_ind are available; the latter is indexed by city.
