    Python 3

    def plusMinus(arr):
    n = 0
    p = 0
    z = 0
    l = len(arr)
    for x in arr:
        if x == 0:
            z+=1
        elif x > 0:
            p+=1
        else:
            n+=1
    
    [print(round(x,6)) for x in [float(p/l),float(n/l),float(z/l)]]

    For Python3 Platform

    I wrote the code from scratch just to get more practice

    def plusMinus(arr):
    positive = len([i for i in arr if i > 0])
    negative = len([i for i in arr if i < 0])
    zero = len([i for i in arr if i == 0])
    
    print(f"{positive/len(arr):.6f}")
    print(f"{negative/len(arr):.6f}")
    print(f"{zero/len(arr):.6f}")

n = int(input())
arr = list(map(int, input().split()))

plusMinus(arr)

    def plusMinus(arr): n = len(arr) positive = neg = zero = 0

    for num in arr:
    if num > 0:
        positive += 1
    elif num < 0:
        neg += 1
    else:
        zero += 1

# Print ratios with 6 decimal places
print("{0:.6f}".format(positive / n))
print("{0:.6f}".format(neg / n))
print("{0:.6f}".format(zero / n))
