Putting it together

Ask for a city, find its coordinates, fetch the weather and print it. Each step is its own small function.

Key points

One function per job
Check for None between steps
Loop so users can check many cities

def get_weather(lat, lon):
    r = requests.get("https://api.open-meteo.com/v1/forecast", timeout=10,
                     params={"latitude": lat, "longitude": lon, "current": "temperature_2m,wind_speed_10m"})
    r.raise_for_status()
    return r.json()["current"]

city = find_city(input("City: "))
if city:
    name, lat, lon = city
    now = get_weather(lat, lon)
    print(f"{name}: {now['temperature_2m']}°C, wind {now['wind_speed_10m']} km/h")
else:
    print("Couldn't find that city.")
