我正在嘗試創建一個顯示火山位置的網絡地圖。我在 Python 中使用 Folium 庫，并使用 HTML 對其進行設計。我也在使用來自 Pandas DataFrame 的數據。但是，當我運行我的代碼時，出現以下錯誤：Traceback (most recent call last): File "webmap.py", line 20, in <module> iframe = folium.IFrame(html=html % (name, name, str(elev)), width=200, height=100)TypeError: not all arguments converted during string formatting這是我的代碼：import foliumimport pandasdata = pandas.read_csv("Volcanoes.txt")latitudes = list(data["LAT"])longitudes = list(data["LON"])elevations = list(data["ELEV"])names = list(data["NAME"])html = """Volcano name:<br><a href="https://www.google.com/search?q=%%22%%s%%22" target="_blank">%s</a><br>Height: %s m"""map = folium.Map(location=[38.58, -99.09], zoom_start=6, tiles="Stamen Terrain")fg = folium.FeatureGroup(name="My Map")for lat, lon, elev, name in zip(latitudes, longitudes, elevations, names): iframe = folium.IFrame(html=html %(name, name, str(elev)), width=200, height=100) fg.add_child(folium.Marker(location=[lat, lon], popup=folium.Popup(iframe), icon=folium.Icon(color="green")))map.add_child(fg)map.save("Map1Advacned.html")Pandas DataFrame 包含有關每座火山的信息，包括其位置（緯度和經度）、海拔和名稱，我在代碼的第一部分將其解析為 Python 數組。有誰知道為什么會出現這個錯誤？任何幫助將非常感激。提前致謝！

我的補充數據是新加坡政府氣象站溫度數據。我已經對其進行了操作以適合您的示例
更改
location和zoom參數，因為新加坡在不同的地方并且小得多;-)您的核心問題是將字符串替換為
html變量。我更喜歡 f-strings，所以將其更改為這個并且它有效。
