getting positional argument error by using folium module

Question

I have a dataset of covid 19 total death, cases, and country names I want to add all details in the map using the folium model but I'm stuck

 ## General Libraries for data analysis
import pandas as pd
import numpy as np
#for visulization
import matplotlib.pyplot as plt
import seaborn as sns
import folium
from matplotlib.lines import Line2D
# read dataset
data = pd.read_csv("covid_data.csv")
data.head()
# maiking map
m = folium.Map(location=[20,0], tiles="OpenStreetMap", zoom_start=2)
for i in range(0,len(data)): 
   folium.Marker(
       location=[data.iloc[i]['Latitude'], data.iloc[i]['Longitude']],
       popup=data.iloc[i]['Total_Case'], +' ' + data.iloc[i]['Total_Death'], +' ' + data.iloc[i][ 'Country'],
    ).add_to(m)
# # Show the map again
m

Error:

File "C:\Users\darshan\AppData\Local\Temp/ipykernel_2388/391102649.py", line 16
    ).add_to(m)
    ^
SyntaxError: positional argument follows keyword argument

In map by using popup I want to display all total death total cases and name of country.

you did not provide reference to your data, so I constructed some sample data of same format as your data frame
the error I received from your code was different
- invalid syntax for concatenation of floats into a string
- replaced with an f-string

solution

for i in range(0, len(data)):
    folium.Marker(
        location=[data.iloc[i]["Latitude"], data.iloc[i]["Longitude"]],
        popup=f'{data.iloc[i]["Total_Case"]} {data.iloc[i]["Total_Death"]} {data.iloc[i]["Country"]}',
    ).add_to(m)
