to retrieve knowledge for.
"""
sitewise = boto3.shopper('iotsitewise')
# restrict for under 10 AssetIds/PropertyIDs/EntryIDs per API name
asset_ids = ['a1','a2','a3'] 
property_ids = ['b1','b2','b3']

"""
Get the beginning and finish timestamps for the date vary of historic knowledge
to retrieve. At the moment set to the final 2 days.
""" 
# Convert present time to Unix timestamp (seconds since epoch)
end_time = int(time.time()) 
# Begin date 2 days in the past
start_time = end_time - 2*24*60*60
"""
Generate a listing of entries to retrieve property worth historical past.
Loops via the asset_ids and property_ids lists, zipping them 
collectively to generate a singular entry for every asset-property pair.
Every entry accommodates a UUID for the entryId, the corresponding 
assetId and propertyId, and the beginning and finish timestamps for 
the date vary of historic knowledge.
"""
entries = []
for asset_id, property_id in zip(asset_ids, property_ids):
  entry = {
    'entryId': str(uuid.uuid4()),
    'assetId': asset_id, 
    'propertyId': property_id,
    'startDate': start_time,
    'endDate': end_time,
    'qualities': [ "GOOD" ],
