Counting overlapping points in a scatter plot

If you draw a scatter plot of the study hours (hours) and quiz scores (score, out of 10) of 12 students, the points of students with the same coordinates overlap and look like one point. You cannot count them in the chart, so count them in the DataFrame.

Print the number of students (the number of rows) on the first line and the number of distinct coordinates (pairs of hours and score) on the second line. Print only the numbers.

Starter code

import pandas as pd

quiz = pd.DataFrame({
    "student": ["S01", "S02", "S03", "S04", "S05", "S06", "S07", "S08", "S09", "S10", "S11", "S12"],
    "hours": [2, 3, 3, 5, 2, 4, 3, 5, 1, 4, 3, 2],
    "score": [6, 7, 7, 9, 6, 8, 7, 9, 5, 7, 7, 6],
})
