Fancy HTML does not display from inside a for loop

[pjandrews]

The following code will only display the first marker of "geo_list" and the html popup will also not be displayed. If I remove the for loop and then the popup is displayed.

Code:

import folium
import pandas as pd
print(folium.file)
print(folium.version)

m = folium.Map(zoom_start=6,tiles='Stamen Toner')

html="""

This is a big popup

"""

geo_list = [(40.712783700000003, -74.005941299999989),
(34.052234200000001, -118.24368490000002),
(41.878113599999999, -87.62979820000001)]

popup = folium.Popup(html=html,max_width=2650)

for lat,lon in geo_list:
print(lat,lon)
folium.Marker([lat,lon], popup=popup).add_to(m)
m

Output:
C:\Program Files\Anaconda3\lib\site-packages\folium_init_.py

Each marker should have its own popup. Like this:

for lat, lon in geo_list:
    popup = folium.Popup(html=html)
    folium.Marker([lat, lon], popup=popup).add_to(m)

In Leaflet this is not necessary, but I don't see an easy way to reuse a Popup object in rendering. When adding a Marker with a Popup to a Map, should we raise an exception if the Popup object already exists? (@ocefpaf )

About opening popups on load, that functionality is coming soon. It's in PR #778.

Thanks a lot for your help @Conengmo
