    I used list comprehension + f-string (Python 3)

    def plusMinus(arr):
     # Write your code here
    p = len([k for k in arr if k>0])
    n = len([i for i in arr if i<0])
    z = len([j for j in arr if j==0])
    
    print(f'{p/len(arr):.6f}')
    print(f'{n/len(arr):.6f}')
    print(f'{z/len(arr):.6f}')

        # Write your code here
    pos = neg = zero = 0
    n = len(arr)
    
    for value in arr:
        if (value == 0):
            zero += 1
        else:
            if (value > 0):
                pos += 1
            else:
                neg += 1
                
    print(round(pos/n, 6))
    print(round(neg/n, 6))
    print(round(zero/n, 6))

    function plusMinus(arr) {
    // Write your code here
    const len = arr.length;
    let pos = 0;
    let neg = 0;
    let zero = 0;
    for(let i in arr) {
        arr[i] > 0 ? pos++ : arr[i] == 0 ? zero++ : neg++
    }
    const firstRatio = (pos / len).toFixed(6)
    const secRatio = (neg / len).toFixed(6)
    const thirdRatio = (zero / len).toFixed(6)
    console.log(firstRatio)
    console.log(secRatio)
    console.log(thirdRatio)
}
