I would like to plot each polygon’s number within the polygon (not usually done). I am able to write the polygon names to a csv file with the following code;

import geopandas as gpd

shp = gpd.read_file("path/to/shapefile")
gdf=shp['shapeName']
gdf.to_csv("ShpNames.csv", index=False) #false, to exclude a number before the name

I have tried to get the index of each polygon and write these to csv with

gdf=shp['index']
gdf.to_csv("Shpindices.csv")

Once I get the indices, I can plot them with basemap.
Question is, is it possible to access the indices this way, or can one actually plot the indices in the shapefile. I cannot find anything, googling pandas tutorials.
