如何用python多次调用exe文件运行不同的结果

#include <iostream>
#include <vector>
#include <fstream>
#include <sstream>
#include <map>
using namespace std;
map<string, double> readKeyValuePairs(const string& fileName) {
    map<string, double> myMap;
    ifstream file(fileName);
    string line;
    while (getline(file, line)) {
        stringstream ss(line);
        string key;
        double value;
        getline(ss, key, ',');
        ss >> value;
        myMap[key] = value;
    }
    return myMap;
}
int main() {
    map<string, double> ans = readKeyValuePairs("../data/file.csv");
    cout << ans.size() << "," << ans["da"]+ans["db"] << ";    " << endl;
}
