title: google maps find_place() positional arguments problem
body: <p>I need to use the googlemaps/google-maps-services-python for a project, and there is the problem. </p>
  
  <p>I want to use find_place():</p>
  
  <pre><code>def find_place(client, input, input_type, fields=None, location_bias=None,
                  language=None):
  </code></pre>
  
  <p>But when I launch my script </p>
  
  <pre><code>import googlemaps
  from datetime import datetime
  
  
  class Place:
  
      def __init__(self, words):
          self.words = words
          self.key = 'Key'
          self.gmaps = googlemaps.Client(key=self.key)
  
  
  place = Place(['place to find'])
  print(place.key)
  loca = place.gmaps.find_place(self.key,"place to find","textquery",['place_id','formatted_address'])
  print(loca)
  
  </code></pre>
  
  <p>there is a problem:</p>
  
  <pre><code>
  Traceback (most recent call last):
    File "gpbapp/program/place.py", line 15, in &lt;module&gt;
      loca = place.gmaps.find_place(place.key,place.words[0],"textquery",['place_id','formatted_address'])
    File "C:\Users\krfou\Documents\OPENCLASSROOMS\p7\env\lib\site-packages\googlemaps\client.py", line 365, in wrapper
      result = func(*args, **kwargs)
    File "C:\Users\krfou\Documents\OPENCLASSROOMS\p7\env\lib\site-packages\googlemaps\places.py", line 94, in find_place
      "the given value is invalid: '%s'" % input_type)
  ValueError: Valid values for the `input_type` param for `find_place` are 'textquery' or 'phonenumber', the given value is invalid: 'disneyland, paris'
  (env)
  
  </code></pre>
  
  <p>If I do</p>
  
  <pre><code>loca = place.gmaps.find_place(place.key,"textquery",['place_id','formatted_address'])
  </code></pre>
  
  <p>it works but I get no result (because input is not there anymore).</p>
  
  <pre><code>{'candidates': [], 'status': 'ZERO_RESULTS'}
  </code></pre>
  
  <p>There is a confusion between the positional arguments, as if there was a hidden argument ... what happens?</p>
