Client=pymongo. Mongoclient (mongodb:// 10.85.39.45:8188,10.85.39.43:8188,10.85.39.31:8188,10.85.39.32:8188,10.85.39.33:8188,10.85.39.34:8188,10.85.32.16:8188,10 .85.32.33:8188,10.85.39.35:8188,10.85.39.27:8188)

2. Initializing the database
Mongo_database = Client[db_name]

3. Initializing tables

STAT_TBL = Mongo_database[stat_tbl_name]

4. Find data by key value in the table

Start_time_doc = Stat_tbl.find_one ({' keyword ': keyword_name})

Start_time_doc may also have a level two key value, need to use start_time_doc[' start_time '] access

5. Updating data in a table

Stat_tbl.update ({' keyword ': keyword_name}, {' $set ': {' start_time ': Timestamp}})
