Use close()method on your MongoClientinstance:
close()在您的MongoClient实例上使用方法：
client = pymongo.MongoClient()
# some code here
client.close()
close()is an alias for disconnect()method:
close()是disconnect()方法的别名：
Disconnecting will close all underlying sockets in the connection pool. If this instance is used again it will be automatically re-opened.
断开连接将关闭连接池中的所有底层套接字。如果再次使用此实例，它将自动重新打开。

the safest way to close pymongo connection would be to use it with 'with'
关闭 pymongo 连接的最安全方法是将它与“with”一起使用
with pymongo.MongoClient(db_config['HOST']) as client:
db = client[ db_config['NAME']]
item = db["document"].find_one({'id':1})
print(item)
