Generate random coordinates in different polygons

I'm new into Python. I want to generate random coordinates inside a set of polygons.

To generate random coordinates inside one Polygon I found this code on Stackoverflor, which works:

def polygon_random_points (poly, num_points):
    minx, miny, maxx, maxy = poly.bounds 
    while len(points) < num_points:
        random_point = Point([random.uniform(minx, maxx), random.uniform(miny, maxy)])
        if (random_point.within(poly)):
            points.append(random_point)
    return points

But now I struggle to achieve a for loop for all of my polygons. They have this data type: geopandas.geoseries.GeoSeries.

Maybe someone can help me.
