如何在 FOLIUM MAP (Python) 中打印 for 循环的索引？

Question

I am writing the following Python code to print numbers beside Folium ICON. I need these indices to be dynamic, meaning, I have a for loop, I want index value to be printed in the HTML line of the code.

for point in range(0, len(coordinates_st)):
    # showing number
    folium.Marker(location=[72.89, -124.59+2], icon=DivIcon(
        icon_size=(150, 36),
        icon_anchor=(7, 20),
        html='<div style="font-size: 18pt;">r{point}</div>',
    )).add_to(map_st)

I want to print number beside the HOME in the image below (loop indexing from for loop, not fixed 1, 2 as currently written in the code).

    for point in range(0, len(coordinates_st)):
        # showing number
        folium.Marker(location=[72.89, -124.59+2], icon=DivIcon(
            icon_size=(150, 36),
            icon_anchor=(7, 20),
            html='<div style="font-size: 18pt;">1, 2</div>',
        )).add_to(map_st)

In this case, the index can be displayed using f-string notation. Since the data is not presented, we can use geopandas data to display the usual markers for the cities of the world, with the index next to them. characters.

import folium
import geopandas as gpd

geo_df = gpd.read_file(gpd.datasets.get_path('naturalearth_cities'))

map_st = folium.Map(location=[50.08528, 14.46403], tiles="OpenStreetMap", zoom_start=4)

for i,row in geo_df.iterrows():
    folium.Marker(location=[row.geometry.y, row.geometry.x+2],
                  icon=folium.DivIcon(
                      icon_size=(150, 36),
                      icon_anchor=(7, 20),
                      html=f'<div style="font-size: 12pt;">{i}</div>',
    )).add_to(map_st)
    folium.Marker(location=[row.geometry.y, row.geometry.x],icon=folium.Icon(color="black", icon="home"),
).add_to(map_st)
map_st
