ValueError:长度不匹配：预期轴有0个元素，新值有7个元素

Question

def getNearbyVenues(names, latitudes, longitudes, radius=500):

    venues_list=[]
    for name, lat, lng in zip(names, latitudes, longitudes):
        print(name)

        url = 'https://api.foursquare.com/v2/venues/explore?&client_id={}&client_secret={}&v={}&ll={},{}&radius={}&limit={}'.format(
            CLIENT_ID, CLIENT_SECRET, VERSION, lat, lng, radius, LIMIT)

        results = requests.get(url).json()["response"]['groups'][0]['items']

        venues_list.append([( name, lat, lng, v['venue']['name'], v['venue']['location']['lat'], v['venue']['location']['lng'], v['venue']['categories'][0]['name']) for v in results])


    nearby_venues = pd.DataFrame([item for venue_list in venues_list for item in venue_list])
    nearby_venues.columns = ['Neighborhood', 'Neighborhood Latitude', 'Neighborhood Longitude', 'Venue', 'Venue Latitude', 'Venue Longitude', 'Venue Category']


    return(nearby_venues)

当我调用上面的函数时

toronto_venues = getNearbyVenues(names=df['Neighborhood'], latitudes=df['Latitude'],longitudes=df['Longitude'])

我犯了以下错误

从堆栈跟踪中我了解到，问题是由nearby_venues数据帧引起的，我分配列的方式是错误背后的主要原因。我能做些什么来解决这个问题
