mongodb

# 连接
client=pymongo.MongoClient(host='127.0.0.1', port=1)
# 选择db
db=client.dbname
# 选择集合
collection = db['tags']
result = collection.find()
for r in result:
    print(r['_id'])
    data = {}
    data['url'] = "url"
    data['name'] = "name"
    # 修改值
    collection.update_one({'_id':r['_id']},{'$set':data})

 

使用pymongo的时候，报错说mongo版本太低，要么降低pymongo版本到3.2，或者升级mongo版本
