How do I round to 2 decimals?

In python, you have floats and decimals that can be rounded. If you care about the accuracy of rounding, use decimal type. If you use floats, you will have issues with accuracy.

All the examples use demical types, except for the original value, which is automatically casted as a float.

To set the context of what we are working with, let's start with an original value.

Original Value

import boto3

def get_instance_name(fid):
    """
        When given an instance ID as str e.g. 'i-1234567', return the instance 'Name' from the name tag.
        :param fid:
        :return:
    """
    ec2 = boto3.resource('ec2')
    ec2instance = ec2.Instance(fid)
