Subsetting by row/column number

The most common ways to subset rows are the ways we've previously discussed: using a Boolean condition or by index labels. However, it is also occasionally useful to pass row numbers.

This is done using .iloc[], and like .loc[], it can take two arguments to let you subset by rows and columns.

pandas is loaded as pd. temperatures (without an index) is available.
