Python 3:

import numpy as np

from collections import Counter

array_size = int(input()) array_numbers = list(map(int,input().split()[:array_size]))

print(array_numbers)

mean = np.mean(array_numbers) print(f"{mean:.1f}")

median = np.median(array_numbers) print(f"{median:.1f}")

counts= Counter(array_numbers)

print(counts)

max_count= max(counts.values())

print(max_count)

modes= [ ] for number, count in counts.items(): if count == max_count: modes.append(number) # print(modes)

print("Final: ",modes)

min_mode = min(modes)

print("min_mode: ",min_mode)

print(min_mode)

Python sol

from collections import Counter
n = int(input())
X = sorted(map(int, input().split()))
c = Counter(X)
print(round(sum(X)/len(X), 1))
if len(X)%2==0:
    print(round((X[len(X)//2]+X[len(X)//2-1])/2, 1))
else:
    print(X[len(X)//2])
najw = max(c.values())
print(min([x[0] for x in c.items() if x[1]==najw]))
