    There is nothing special about it, the code is not very efficient. - looking at the prettiness of the code, I would say it's around decent - pretty. It's very readable, and understandable. Compared to this s*** for instance: (I didn't write it)

    print("{:6f}\n{:6f}\n{:6f}".format(len(list(filter(lambda x:x>0,arr)))/len(arr),len(list(filter(lambda x:x<0 , arr)))/len(arr),len(list(filter(lambda x:x==0,arr)))/len(arr)))

    This was my solution:

    n = int(input())
arr = [int(x) for x in input().split()]

positive = 0
negative = 0
zeroes = 0

for i in arr:
    if i > 0:
        positive += 1
    elif i < 0:
        negative += 1
    else:
        zeroes += 1

Length = len(arr)
print(positive/Length)
print(negative/Length)
print(zeroes/Length)

    the best possible performance, and it's easy to read, and just looks overall pretty.
