title: Check a dataframe column to see if a bool if True/False, if False, geocode only those values
body: <p>I am using the [geocoder python API library][1]. I have a pandas dataframe column of boolean True/False based on if I already have that particular address geocoded or not. Is there a way to modify my existing code to geocode based on if I have it geocoded or not?</p>
  
  <p>Right now all it does is print a True statement and then geocodes everything, regardless of the boolean I have. Help Please!</p>
  
  <p>Here is another way to put it:</p>
  
  <p>I have a dataframe of Tweets. If a Tweet was geocoded, I have marked that Tweet with a True (if it has been geocoded) or False (If it has not been geocoded). What I'm trying to do is check if the column is True, print out that row. Else if that row is False, then send it into my for loop to be geocoded. I will edit the original post for an input. </p>
  
  <p>Here is my exisiting code: </p>
  
  <pre><code>for d in tweets2['Exist']:
      if d is True:
          print d
      elif d.any() is False:
          coord = []
          for index, row in tweets2.iterrows():
              print(row['location_x'])
              time.sleep(1.01)
              g = geocoder.osm(row['location_x'])
              geo = g.latlng
              print(geo)
              coord.append(geo)
      else:
          pass
