C++ :

#include<iostream>
#include<iomanip>
#include<cstring>
#include<ctime>
#include<cstdio>
using namespace std;
int main()
{
	//freopen("test10.in","r",stdin);
	//freopen("test10.out","w",stdout);
    double a,sum=0;
    int zs=0,fs=0;
    while(1)
	{
		cin>>a;
		if(a==0)
		{
			printf("%d %d %0.3lf\n",zs,fs,sum);
			return 0;
		}		
		if(a>0) zs++;
		else fs++;
		sum+=a;
	}
//	fclose(stdin);
	//fclose(stdout);
	return 0;
}

Python :

List = raw_input().split()
x = 0.0
Cnt1 = 0
Cnt2 = 0
Sum = 0.0
for String in List :
    x = float(String)
    if x == 0 :
        print '%d %d %.3f\n' % (Cnt1, Cnt2, Sum)
        break
    if x > 0 :
        Cnt1 += 1
    if x < 0 :
        Cnt2 += 1
    Sum += x
