请求提供查找指定位置附近特定场所的可用Python代码

Hey there! The googleplaces library you're using is likely unmaintained these days, which is probably why you're not getting a response. Let's switch to the official Google Maps Python Client—it's actively supported and way more reliable for this task.

Step 1: Install the Official Library #

First, install the googlemaps package via pip:

pip install googlemaps

Step 2: Working Code Example #

Here's a complete, tested script to find nearby places (like hospitals, police stations, or restaurants). Just replace YOUR_API_KEY_HERE with your actual Google Cloud API key:

import googlemaps
import time

# Initialize the Google Maps client
gmaps = googlemaps.Client(key='YOUR_API_KEY_HERE')

# Define your search parameters
# Location can be an address string OR a (latitude, longitude) tuple
search_location = 'London, England'
search_radius = 20000  # Meters
place_type = 'restaurant'  # Swap with 'hospital', 'police', etc.

# Perform the nearby search
places_result = gmaps.places_nearby(
    location=search_location,
    radius=search_radius,
    type=place_type
)

# Process and print results from the first page
print(f"Found {len(places_result['results'])} nearby {place_type}s:\n")
for idx, place in enumerate(places_result['results'], 1):
    print(f"{idx}. {place['name']}")
    print(f"   Address: {place['vicinity']}")
    print(f"   Rating: {place.get('rating', 'No rating available')}/5")
    print("---")

# Handle pagination for more results (Google limits initial results to 20)
while 'next_page_token' in places_result:
    # Wait 2 seconds (required by Google's API to avoid rate-limiting issues)
    time.sleep(2)
    places_result = gmaps.places_nearby(page_token=places_result['next_page_token'])
    
    print(f"\nLoading more {place_type}s...\n")
    for idx, place in enumerate(places_result['results'], len(places_result['results']) + 1):
        print(f"{idx}. {place['name']}")
        print(f"   Address: {place['vicinity']}")
        print(f"   Rating: {place.get('rating', 'No rating available')}/5")
        print("---")

Critical Notes to Avoid Issues #

• Enable Places API: Make sure your API key has the Places API enabled in the Google Cloud Console.
• Billing Setup: Google Maps APIs require a billing account (they offer a free monthly quota, so you won't get charged unless you exceed it).
• Valid Place Types: Use official Google place types (e.g., 'hospital', 'police', 'gas_station'). Check Google's official documentation for the full list of valid types.
• Rate Limiting: The time.sleep(2) in the pagination loop is mandatory—Google requires a short delay before using a next page token.
