I'm in the geopanda tutorial, in the plotting with folium section (add markers).
I currently have a geodataframe called geo_df and my code is as follows
geo_df_list = [[point.xy[1][0], point.xy[0][0]] for point in geo_df.geometry ]
# Iterate through list and add a marker for each volcano, color-coded by its type.
i = 0
for coordinates in geo_df_list:
#assign a color marker for the type of volcano, Strato being the most common
if geo_df.Type[i] == "Stratovolcano":
type_color = "green"
elif geo_df.Type[i] == "Complex volcano":
type_color = "blue"
elif geo_df.Type[i] == "Shield volcano":
type_color = "orange"
elif geo_df.Type[i] == "Lava dome":
type_color = "pink"
else:
type_color = "purple"
# Place the markers with the popup labels and data
map.add_child(folium.Marker(location = coordinates,
popup =
"Year: " + str(geo_df.Year[i]) + '<br>' +
"Name: " + str(geo_df.Name[i]) + '<br>' +
"Country: " + str(geo_df.Country[i]) + '<br>'
"Type: " + str(geo_df.Type[i]) + '<br>'
"Coordinates: " + str(geo_df_list[i]),
icon = folium.Icon(color = "%s" % type_color)))
i = i + 1
I don't understand why I get this error

The above exception was the direct cause of the following exception:
