Outputting Rows by Index
Pandas has plenty of valuable tools; for instance, it allows you to output only specific rows. We will work with the same dataset.
data[0:3]- outputs the rows from zero to three0,1,2, for all columns (pay attention, this method doesn't include the last index);data[:3]- outputs the rows from zero to three0,1,2, for all columns;data[997:999]- outputs rows from 997 to 999:997and998, for all columns (this is the last row);data[997:]- outputs rows from 997 to the last one:997,998,999, for all columns;data[:]- outputs all rows of the datasetdatafor all columns.
