why does my geolocation it is not working?

Question

The duty of my function is to calculate the distance from my business to any address (at the end (print fucntion) I put an example of an address)). I don´t know why it is not working, it says something about traceback error.

The first part of my function, converts from address to coordinates. The second part calculate the distance.

THIS IS THE CODE

import math
from geopy.geocoders import Nominatim

def Distancia(direccion_domicilio):
    geolocator = Nominatim(user_agent="specify_your_app_name_here")
    location = geolocator.geocode(direccion_domicilio)
    latylon=(location.latitude, location.longitude)


    rad=math.pi/180
    dif_lat = 20.6072848-(latylon[0])
    dif_long = -103.4160099-(latylon[1])
    radio=6372.795477598
    a=(math.sin(rad*dif_lat/2))**2 + math.cos(rad*location.latitud)*math.cos(rad*20.6072848)*(math.sin(rad*dif_long/2)**2)
    distancia=2*radio*math.asin(math.sqrt(a))
    return distancia

print(Distancia("Avenida Guadalupe, Real Guadalupe, Jardines de Chapalita, Zapopan, Jalisco, 45030, México"))

THIS IS THE ERROR MESSAGE

You did not perform a whole installation process. Traceback tells you what is happening. It says that there is a problem with SSL certificate. geopy library retrieves data from web (Nomitatiom in your case). Take a look at this documentation: https://geopy.readthedocs.io/en/stable/#geopy.geocoders.options and option called default_ssl_context. You should use this code at the beginning of yours code (from the above documentation):

to use SSL use:

    import ssl
    import certifi
    import geopy.geocoders
    ctx = ssl.create_default_context(cafile=certifi.where())
    geopy.geocoders.options.default_ssl_context = ctx

to disable SSL (not recommended, may not even work for some geo providers):

    import ssl
    import geopy.geocoders
    ctx = ssl.create_default_context()
    ctx.check_hostname = False
    ctx.verify_mode = ssl.CERT_NONE
    geopy.geocoders.options.default_ssl_context = ctx

why does my geolocation it is not working?
