Student Report From Input

Build a dict of dicts from the input and report on it. Input: the first line is a whole number n; then for each of the n students come four lines, a name and then three grades as decimal numbers; read everything with a bare input(), no prompts, using range(n) for the students. Store each student as an inner dict with the key grades holding the three grades as a list, under the name in the outer dict. Then print one line per student in input order in the form <name>: <average> with the average of their grades to two decimals, computed with sum and len, and finally the line Top: <name> for the student with the highest average, found with a loop and no max.
