如何将boto3过滤器用于布尔值

Question

I'm using boto 3 in python 3.5.2 trying to describe ec2 images. The doc says one of the available filters is 'is-public':

is-public - A Boolean that indicates whether the image is public.

But the Filter syntax wants a list of strings - and only a list of strings - for the Value. If I try passing a Boolean, it gives me a type error:

Invalid type for parameter Filters[0].Values[0], value: False, type: <class 'bool'>, valid types: <class 'str'>

My code:

  response = session.client("ec2").describe_images(
Filters=[
  {'Name': 'is-public',
   'Values': [False],
  },

How do I pass a Boolean filter when it will only accept a string?

Thanks... Bill

This works for me... use lower case.

    ami_filter = [{"Name": "platform", 'Values': ["windows"]}, 
        {"Name": "virtualization-type", 'Values': ["hvm"]}, 
        {"Name": "image-type", 'Values': ["machine"]},
        {"Name": "architecture", 'Values': ["x86_64"]},
        {"Name": "state", 'Values': ["available"]},
        {"Name": "is-public", 'Values': ['false']}]

    ami_owners = ['amazon']
    results = client.describe_images(Filters=ami_filter, Owners=ami_owners)
