<div class =“post-text”itemprop =“text”>
  <P>
    这应该会让你知道如何做到这一点
  </p>
   <pre>
    <code>
      import pymongo

client = pymongo.MongoClient('yourHost', 30000) # adjust to your needs
db = client.so
coll = db.yourcollection

# show initial data
for doc in coll.find():
    print(doc)

# update data
places_visited = [
    "Palace of Dob",
    "Palace of Victoria",
    "Sahara Desert"
]
coll.update({}, { "$set": { "Places Visited": places_visited } }, multi=True)

# show updated data
for doc in coll.find():
    print(doc)

</code>
  </pre>
  <P>
    对于您的样本数据，应该提供与此类似的输出
