Implement Multiple conditions in more pythonic way in the JSCode part

Custom Components streamlit-aggrid
1

Dear friends,
I am currently trying to find a scalable approach for the following situation. Suppose you have the following frame

import pandas as pd
import numpy as np
import streamlit as st
from st_aggrid import AgGrid
testFrame=pd.DataFrame({"name":["Albert","Mike","John","Laura"],"Mail":["albert@testmail.com",
"<Mike@testmail.com>","_John_@testmail.com","laura@gmail,com"]})

gb = GridOptionsBuilder.from_dataframe(EMail)



cellsytle_jscode_mail = JsCode("""
                                    function(params){

gb.configure_column("Mail", cellStyle=cellsytle_jscode_mail,editable=True)
grid_return=AgGrid(testFrame, editable=True)
General=grid_return["data"]

Question: How can I modify the JS Code part in a way to check if

param.vaule is in ["<",">"]  #more python way of writing

instead of typing multiple if conditions in the cell_jscode_mail expression

Any idea how to write it more compact, meaning comparing the params.value with a list I could create?
