boto3 Autoscaling creating scale up and down policy and cloudwatch

I am able to create Launch configuration and Autoscale using boto3. But How to create scale up alarm and scale down policy and cloudwatch alarm. On internet i am only able to find docs to configure it using boto2 but i need boto3 Over boto2 we can do like below and it works. But i need to acheive same using boto3. I am able to find put_scaling_policy function but not able to understand the example. Can someone suggest a working config using boto3. Below is the boto2 code

#Defining Scale Up and Scale down policy
from boto.ec2.autoscale import ScalingPolicy
scale_up_policy = ScalingPolicy(
            name='scale_up', adjustment_type='ChangeInCapacity',
            as_name=ag.name, scaling_adjustment=1, cooldown=180)
scale_down_policy = ScalingPolicy(
            name='scale_down', adjustment_type='ChangeInCapacity',
            as_name=ag.name, scaling_adjustment=-1, cooldown=180)

#Creating the Autoscale policy
conn.create_scaling_policy(scale_up_policy)
conn.create_scaling_policy(scale_down_policy)

#Creating Cloudwatch alarm
import boto.ec2.cloudwatch
cloudwatch = boto.ec2.cloudwatch.connect_to_region(region)


#Create an alarm for when to scale up, and one for when to scale down.
from boto.ec2.cloudwatch import MetricAlarm
scale_up_alarm = MetricAlarm(
            name='scale_up_on_cpu', namespace='AWS/EC2',
            metric='CPUUtilization', statistic='Average',
            comparison='>', threshold='70',
            period='60', evaluation_periods=2,
            alarm_actions=[scale_up_policy.policy_arn],
            dimensions=alarm_dimensions)
cloudwatch.create_alarm(scale_up_alarm)

scale_down_alarm = MetricAlarm(
            name='scale_down_on_cpu', namespace='AWS/EC2',
            metric='CPUUtilization', statistic='Average',
            comparison='<', threshold='40',
            period='60', evaluation_periods=2,
            alarm_actions=[scale_down_policy.policy_arn],
            dimensions=alarm_dimensions)
cloudwatch.create_alarm(scale_down_alarm)

I have the same problem, any idea?
