如何从Google Geocoding API返回的Python字典中提取经纬度？

Hey there! Glad you’ve already parsed the API response into a dictionary—you’re most of the way there. Here’s a straightforward way to pull out the latitude and longitude values:

Step-by-Step Extraction #

The geocoding response nests location data in this path: results → (first result item) → geometry → location. Since the API returns a list of results (with the first being the most accurate match for your address), we’ll target that first item.

Here’s the code to do it:

# Grab the top matching result from the response
top_result = response_data['results'][0]

# Navigate to the location coordinates section
location_data = top_result['geometry']['location']

# Extract latitude and longitude
latitude = location_data['lat']
longitude = location_data['lng']

# Print or use the values as needed
print(f"Latitude: {latitude}")
print(f"Longitude: {longitude}")

Shortened Version (For Brevity) #

If you prefer more concise code, you can condense this into one line:

lat, lng = response_data['results'][0]['geometry']['location'].values()

Critical Pre-Check: Verify API Success #

Before extracting data, always confirm the API call worked by checking the status field. This avoids errors if the address couldn’t be geocoded:

if response_data['status'] == 'OK':
    # Run your extraction code here
    lat, lng = response_data['results'][0]['geometry']['location'].values()
    print(f"Coordinates: ({lat}, {lng})")
else:
    print(f"Geocoding failed with status: {response_data['status']}")

This will get you the exact latitude and longitude for the Empire State Building from your provided response.
