 Example::
 
   >>> import Geohash
-  >>> print 'Geohash for 42.6, -5.6:', Geohash.encode(42.6, -5.6)
+  >>> print('Geohash for 42.6, -5.6: ' + Geohash.encode(42.6, -5.6))
   Geohash for 42.6, -5.6: ezs42e44yx96
 
 You can specify an arbitrary precision when encoding. The precision
 determines the number of characters in the Geohash::
 
-  >>> print 'Geohash for 42.6, -5.6:', Geohash.encode(42.6, -5.6, precision=5)
+  >>> print('Geohash for 42.6, -5.6: ' + Geohash.encode(42.6, -5.6, precision=5))
   Geohash for 42.6, -5.6: ezs42
 
 Decoding a Geohash returns a (latitude, longitude) tuple::
 
-  >>> print 'Coordinate for Geohash ezs42:', Geohash.decode('ezs42')
+  >>> print('Coordinate for Geohash ezs42: ' + str(Geohash.decode('ezs42')))
   Coordinate for Geohash ezs42: ('42.6', '-5.6')
 
 The Geohash module also provides exact decoding with error margin
 results. The decode_exactly function returns a tuple of four float
 values; latitude, longitude, latitude error margin, longitude error
 margin::
 
-  >>> print 'Exact coordinate for Geohash ezs42:\n', Geohash.decode_exactly('ezs42')
+  >>> print('Exact coordinate for Geohash ezs42:\n' + str(Geohash.decode_exactly('ezs42')))
