list RDS snapshot created today using Boto 3

问题

I am doing a Python Lambda function to describe list of RDS snapshots created today. The challenge is how to convert the datetime.datetime.today() into a format which RDS client understands?

UPDATE: I have implemented some changes suggested, I have added a string variable to convert the date expression into format which Boto3 RDS understands.

'SnapshotCreateTime': datetime(2015, 1, 1),

today = (datetime.today()).date()
rds_client = boto3.client('rds')
snapshots = rds_client.describe_db_snapshots(SnapshotType='automated')

harini = "datetime("+ today.strftime('%Y,%m,%d') + ")"
print harini

print snapshots

for i in snapshots['DBSnapshots']:
    if i['SnapshotCreateTime'].date() == harini:
        print(i['DBSnapshotIdentifier'])
        print (today)

it is still unable to retrieve list of automated snapshots created today

回答1:

SnapshotCreateTime is a datetime.datetime object. So, you can just do i['SnapshotCreateTime'].date() to get the date.

import boto3
from datetime import datetime, timezone

today = (datetime.today()).date()
rds_client = boto3.client('rds')
snapshots = rds_client.describe_db_snapshots()

for i in snapshots['DBSnapshots']:
    if i['SnapshotCreateTime'].date() == today:
        print(i['DBSnapshotIdentifier'])
        print (today)
