How to scrap things in

Question

Please fill free to tell me that i'm new, i started python last week, so sorry if that question is a neophyt one. I'm asking how to scrap something with a "<li" html tag selection. In the following website (https://www.investing.com/indices/france-40-technical) i would like to scrap the RSI value at the bottom left table for all the possible time units under "CAC40 Technical Analysis".

In my novice opinion, i have to select the "li" that i want into python, but i can't find how to.

But i can't find how to select time units in those tags. You could find my code below.

Could you help the debutant i am ?

Thanks !

    print("Réponse site ok")

    soup=BeautifulSoup(reponse.text,"html.parser")

    cac40=soup.find('span',{'id':'last_last'}).get_text().strip()

    print(cac40)

    soup.select()
    print(rsicac40_5hours_class)

Concerning the error code, it's the following one :

"
