Import math. Calculate math.isqrt(144) on line 1 and math.ceil(4.2) on line 2, and print both:

Import statistics. Given sales = [1200, 3400, 850, 4100, 2900], print statistics.median(sales):

From datetime import date, timedelta. Given inv = date(2026, 4, 15), compute due = inv + timedelta(days=30) and print due:

From datetime import date. Compute the days between start = date(2026, 4, 1) and end = date(2026, 4, 25) using (end - start).days. Print the days:

From collections import Counter. Given reps = ["Asha", "Ravi", "Asha", "Priya", "Asha"], count with counts = Counter(reps). Print counts["Asha"]:

From collections import Counter. Given cats = ["Desk", "Chair", "Desk", "Desk", "Lamp"], print Counter(cats).most_common(1)[0][0]:

Import csv, io. Given csv_text = "Rep,Sales\nAsha,1400\nRavi,2200\n", parse with csv.DictReader(io.StringIO(csv_text)) and print the total sales sum 3600:

Import csv, io. Create out = io.StringIO(), create writer = csv.writer(out), write row ["Rep", "Rev"] and row ["Asha", "1200"]. Print out.getvalue().strip():
