title: Using my Google Geocoding API key with Python geocoder
body: <p>I'm a beginner at Python and I've been working to geocode a database using Pandas and Geocoder on Jupyter.</p>
  
  <p>Since the df is a little long (around 3000 rows), I'd like to use Google's Geocoding API.</p>
  
  <p>I've already created a free key, but I have no idea what I'm supposed to do with it. Help?</p>
  
  <p>By the way, my code looks like this:</p>
  
  <pre><code>import geocoder
  import pandas as pd
  
  geo = geocoder
  
  df=pd.read_excel('hsp2.xlsx')
  
  df['Coordinates']=df['Address'].apply(geo.google).apply(lambda x: x.latlng if x != None else None)
  
  df.to_csv('output.csv', sep='|', encoding='iso8859_15')
  </code></pre>
