User entering three different numbers, but program summarizes only the sum of the positive numbers

I need a program which when a user types three different random numbers, the program only calculates and summarizes the sum of the positive ones and gives me an answer!

Thank you!

nsum = 0
nums = tuple(map(lambda n: float(n), input('Input 3 numbers:\n').split(' ')))

for item in nums:
    if item > 0:
        nsum += item

print(nsum)

You can put more than 3 numbers. Also, type them in with a space in between, like this:

1 -20 3

the following program is written in C:

#include <stdio.h>
int main()
{
int a, b, c, s=0;
printf("enter any three numbers:  ");
scanf("%d%d%d", &a, &b, &c);
if(a>0)
s=s+a;
if(b>0)
s=s+b;
if(c>0)
s=s+c;
printf("%d", s);
}

#include <iostream>
using namespace std;

double somma (double a, double b, double c)
{
  double sum = 0;
  if (a > 0) sum += a;
  if (b > 0) sum += b;
  if (c > 0) sum += c;
  return sum;
}

int main()  {
  double x, y, z;
  cout << "Inserire 3 numeri : ";
  cin >> x >> y >> z;
  cout << "La somma dei numeri positivi รจ : " << somma(x,y,z);
}

#include <stdio.h>

int main(){

int num1, num2, num3, sum = 0;

printf("Enter three numbers:  ");
scanf("%d %d %d", &num1, &num2, &num3);

if(num1>0)
sum += num1;

if(num2>0)
sum += num2;

if(num3>0)
sum += num3;

printf("Sum of numbers entered = %d", sum);

return 0;

This is written in c using functins, hope it helps:

#include <stdio.h>
int add(int x,int y,int z);
int main()
{
  int x,y,z,sum;
  printf("Enter 3 no's: ");
  scanf("%d %d %d", &x,&y,&z);
  sum=add(x,y,z);
  printf("Addition of +ve no's is:%d",sum);
  return 0;
}
int add(int x,int y,int z)
{
    int sum,res;
    if(x>0)
    sum+=x;
    if(y>0)
    sum+=y;
    if(z>0)
    sum+=z;
    return sum;
}

#include<iostream>

using namespace std;

int main()

{

int i,a[3],s=0;

for(i=0;i<3;i++)

{

cin>>a[i];

}

for(i=0;i<3;i++)

{

if(a[i]>0)

{

s+=a[i];

}

}

cout<<s;
