Build a Marks and Results Analyser

60 min · Medium

Back to syllabus (Collections Mini Projects)

Every school and training centre turns a pile of marks into a rank list, subject averages and a pass or fail result, and Python's collections make that short and clear.

What you will learn

Group raw mark records into nested dictionaries keyed by student and subject
Count grades and repeated marks with Counter, and group marks by subject with defaultdict
Sort rows by several fields and assign shared ranks to tied totals
Print an aligned report that a teacher could read at a glance
