EC2 Describe Instances produced different format from CLI vs Boto3
I am getting a different output for dates depending on how I run the ec2 describe-instances command.
From CLI, the following output is given:
"BlockDeviceMappings": [
{
"DeviceName": "/dev/sda1",
"Ebs": {
"Status": "attached",
"DeleteOnTermination": false,
"VolumeId": "vol-032ed502806c9e847",
"AttachTime": "2018-11-08T21:30:24.000Z"
From PyCharm, I get the following:
'BlockDeviceMappings': ['DeviceName': '/dev/sda1',
'Ebs': 'AttachTime': datetime.datetime(2018, 7, 14, 16, 44, 31, tzinfo=tzutc()),
'DeleteOnTermination': True,
'Status': 'attached',
'VolumeId': 'vol-096cd0ee0ace156df',
The "AttachTime" is not converting to a date. When I run an operation and tried to write the output dictionary to a JSON file, the following error comes up:
TypeError: Object of type datetime is not JSON serializable
I tried importing datetime and that doesn't work. Why is this happening? And is there a way to fix this so the formatting is the same when using both opeartion?

Usedatetime.strftime(format)to convert the datetime object to a string. See: Python datetime to string without microsecond component
