Maps Folium Python

Question

import folium 
import pandas as pd

df_bedarf = pd.read_csv('C:/Users/xxxxx/Desktop/xxxxxx/xxxxxxx.csv', sep = ";")
df_bedarf.head()

df_locations = df_bedarf[["Latitude", "Longitude"]]
location_list = df_locations.values.tolist()
location_list_size= len(location_list)

map_points = folium.Map(location = [47.57087, 13.43828], zoom_start = 7)

for point in range(0, location_list_size):
    folium.circle(
        location = location_list[point],
        popup=df_locations["suburb"][point] + ": " + df_locations["Sort"][point],
        radius = str(df_locations["t/a"][point]*100)
        color="#17cbef",
        fill=True,
        opacity =0.8,
        fill_color="#17cbef,
        stroke = True, 
        weight = 1.0,
    ).add_to(map_points)
    
map_points

This is the head():

I get a syntax error???

Where is my error?

Answer 1

The cause of the error was probably that the latitude and longitude of the location information was not in list format. It is easier to handle the data frame with df.itertools(), so I modified the code. Also, the size of the circle is referenced by adding a new column as appropriate, so please fix this. The color and transparency of the circles have also been modified to make them easier to locate.

import pandas as pd
import numpy as np
import io

data = '''
  Suburb  Sort    t/a     Latitude    Longitude
0   Wien    CC  2272    48.201900   16.370000

df_locations = pd.read_csv(io.StringIO(data), delim_whitespace=True)
df_locations['points'] = np.random.randint(100, 500, (5,))

import folium
