Failed geolocalization with Geopy, Nominatim: TypeError: 'NoneType' object is not subscriptable

Question

I am trying to use module Geopy, function Nominatim to geolocalize a list of addresses (contained inside a CSV file).
Here is my code:

import pandas as pd

from geopy.geocoders import Nominatim 

df = pd.read_csv('incidenti genova 3.csv', delimiter=';', error_bad_lines=False)
indirizzi = df.descrizione_strada

nom=Nominatim(user_agent="my-application") 

coordinate=[]

for element in indirizzi:
    print(element)
    target1=nom.geocode(element)[1]
    print(target1)
    coordinate.append(target1)

When I run it, it prints the first address of my list, then I get this error:

TypeError                                 
Traceback (most recent call last) <ipython-input-9-765a06164536> in <module>()
     13     print(element)
     14 
---> 15     target1=nom.geocode(element)[1]
     16     print(target1)
     17     coordinate.append(target1)

TypeError: 'NoneType' object is not subscriptable

I found out it means that it failed geolocalizing the address because the address is not complete enough.
What I want is the code to skip the elements of the list it could not geolocalize and go on printing the others.

How can I do it?

Well you are missing one of the very important fundamentals of coding, i.e the try... except statements

You probably wanna do something like this:

for element in indirizzi:
  try: 
   print(element)
   target1=nom.geocode(element)[1]
   print(target1)
   coordinate.append(target1)
  except NoneType:
   pass
