How can I have a C++ set with more than 1 data type?

Trying to learn C++ coming from Python, and in python a set can have multiple types. How do I do this in C++? I'm specifically trying to have a set with both integers and strings. For example:

#include <set>
#include <string>
using namespace std;

int main() {
    set<int, string> s;
    s.insert(1);
    s.insert("string");
    
}
