Calling Python Class from C without destroying the object

Question

Suppose I have a simple Python File like

myFile.py

class Bar():
    def __init__(self):
        self.foo = []

    def add_to_list(self, elem):
        self.foo.append(elem)

    def return_first_value(self):
        return self.foo[0]

How do I create this class in C as an object and manipulate it several times without destroying it? In Pseudo-Code:

pseudo_code

pyFile = import_file("myFile.py")
pyObject = create_class("Bar")
pyObject.add_to_list(2)
printf(pyObject.return_first_value()) // returns 2

pyObject.add_to_list(5)
printf(pyObject.return_first_value()) // still returns 2

I searched in the stackoverflow community and found various references to the Python/C API which helped me calling a method (e.g. here). But I am kind of stuck in creating an object and calling the method within.

Here is what I tried:

test.c

#include <Python.h>
#include <stdio.h>

int main() {

    Py_Initialize();

    // Import Module
    PyObject* myModule = PyImport_ImportModule("myFile");

    // Create object
    PyObject* myClass = PyObject_GetAttrString(myModule, "Bar");
    PyObject* object = PyObject_CallNoArgs(myClass); // I don't believe this creates the object of Bar

    //Add number to list
    PyObject* add = PyObject_GetAttrString(object,"add_to_list");
    PyObject* args = PyTuple_Pack(1,PyFloat_FromDouble(2.0));
    PyObject* result = PyObject_CallObject(add,args);

    return 0;
}

Any help is very appreciated!
