PandasdrillRows and columns with loc
A pandas exercise from Pandasdrill. Solve it with a Python editor in your browser running real pandas, and it is checked the moment you submit.
The task
Use `.loc` to select the employees in the Engineering department, keeping only the `name` and `years` columns (in that order).
What this exercise teaches
emp.loc[rows, columns] selects both at once. The row part is a boolean mask for the department, and the column part is a list of labels, so the result keeps the original index of each engineer.
A hint if you get stuck
loc takes two parts separated by a comma: which rows (a mask works) and which columns (a list of names).
