Error Using geopy library - python-3.x

Question

I have the following question, I want to set up a routine to perform iterations inside a dataframe (pandas) to extract longitude and latitude data, after supplying the address using the 'geopy' library.
The routine I created was:
import time
from geopy.geocoders import GoogleV3
import os
arquivo = pd.ExcelFile('path')
df = arquivo.parse("Table1")
def set_proxy():
proxy_addr = 'http://{user}:{passwd}#{address}:{port}'.format(
user='usuario', passwd='senha',
address='IP', port=int('PORTA'))
os.environ['http_proxy'] = proxy_addr
os.environ['https_proxy'] = proxy_addr
def unset_proxy():
os.environ.pop('http_proxy')
os.environ.pop('https_proxy')
set_proxy()
geo_keys = ['AIzaSyBXkATWIrQyNX6T-VRa2gRmC9dJRoqzss0'] # API Google
geolocator = GoogleV3(api_key=geo_keys )
for index, row in df.iterrows():
location = geolocator.geocode(row['NO_LOGRADOURO'])
time.sleep(2)
lat=location.latitude
lon=location.longitude
timeout=10)
address = location.address
unset_proxy()
print(str(lat) + ', ' + str(lon))
The problem I'm having is that when I run the code the following error is thrown:
GeocoderQueryError: Your request was denied.
I tried the creation without passing the key to the google API, however, I get the following message.
KeyError: 'http_proxy'
and if I remove the unset_proxy () statement from within the for, the message I receive is:
GeocoderQuotaExceeded: The given key has gone over the requests limit in the 24 hour period or has submitted too many requests in too short a period of time.
But I only made 5 requests today, and I'm putting a 2-second sleep between requests. Should the period be longer?
Any idea?

api_key argument of the GoogleV3 class must be a string, not a list of strings (that's the cause of your first issue).
geopy doesn't guarantee the http_proxy/https_proxy env vars to be respected (especially the runtime modifications of the os.environ). The advised (by docs) usage of proxies is:
geolocator = GoogleV3(proxies={'http': proxy_addr, 'https': proxy_addr})
PS: Please don't ever post your API keys to the public. I suggest to revoke the key you've posted in the question and generate a new one, to prevent the possibility of it being abused by someone else.
