Hello,

just a minor docs improvement

in https://github.com/mongodb/mongo-python-driver/blob/master/README.rst

print might changed to work both with Python 2.7 and Python 3.x

>>> for item in db.my_collection.find():
... print(item["x"])
...
10
8
11
>>> db.my_collection.create_index("x")
u'x_1'
>>> for item in db.my_collection.find().sort("x", pymongo.ASCENDING):
... print(item["x"])

Kind regards
