How do I convert two floats of latitude and longitude into Google Maps latlng?

Question

I have the latitude and longitude of places in a dataframe. I am looking to get the zip code using Google Maps API. Now I am trying to write a loop to do this and it won't work. The problem is the gmaps variable latlng How do I get two floats that are my variables into one variable that is latlng?

I have successfully done this went I "hardcode" in the coordinates.

for index, row in bike_df.iterrows():

    lat = row["Starting Station Latitude"]
    long = row["Starting Station Longitude"]


    target_url = ('https://maps.googleapis.com/maps/api/geocode/json?'
              'latlng=34.052898,-118.241562&key={0}').format(gkey)
    response = requests.get(target_url).json()

    try:
        print(response['results'][0]['address_components'][7]['long_name'])
    except:
        print(f"Could not {index} find zip")

for index, row in bike_df.iterrows():

    lat = row["Starting Station Latitude"]
    long = row["Starting Station Longitude"]


    target_url = ('https://maps.googleapis.com/maps/api/geocode/json?'
              'latlng=lat,long&key={0}').format(gkey)
    response = requests.get(target_url).json()

    try:
        print(response['results'][0]['address_components'][7] . 
         ['long_name'])
    except:
        print(f"Could not {index} find zip")

It just runs and runs without any output.

Your lat and long variables aren't being inserted in the target_url string. You'll need to do something like:

target_url = ('https://maps.googleapis.com/maps/api/geocode/json?'
          'latlng={lat},{long}&key={gkey}').format(lat=lat,long=long,gkey=gkey)

This works. Thank you! I thought it had to be one variable. – KPH3802 Jul 10 '19 at 20:45

You should use, like you did with gkey, concatate your variable. You can do it in several way.

For example:

target_url = ('https://maps.googleapis.com/maps/api/geocode/json?'
          'latlng='+str(lat)+','+str(long)+'&key={0}').format(gkey)

or somehting like

target_url = ('https://maps.googleapis.com/maps/api/geocode/json?latlng={0},{1}&key={2}').format(lat, long, gkey)

Maybe try this?

import pandas as pd

df = pd.DataFrame({'lat':[34.052898,34.052898,34.052898],
     'long':[-118.241562,-118.241562,-118.241562]})

df

for index, row in df.iterrows():

    latlng = lat + long

    print(latlng)

[34.052898, -118.241562] [34.052898, -118.241562] [34.052898, -118.241562]

lat = row["Starting Station Latitude"]
    long = row["Starting Station Longitude"]


    target_url = ('https://maps.googleapis.com/maps/api/geocode/json?'
              'latlng=lat,long&key={0}').format(gkey)
    response = requests.get(target_url).json()

    try:
        print(response['results'][0]['address_components'][7] . 
         ['long_name'])
    except:
        print(f"Could not {index} find zip")
