Your data looks like Json.
First use the _json_ module to convert the _string_ into a _Python data
structure_.
Then you can iterate over it. My example is a nested loop. Maybe
you've more than one element inside the list.
import json
# the string looks like json
JSON_DATA = """[
{"itemNumber":"75-5044","inventory": [
{"warehouseCode":"UT-1-US","quantityAvailable":0.0000000000000},
{"warehouseCode":"KY-1-US","quantityAvailable":0.0000000000000},
{"warehouseCode":"TX-1-US","quantityAvailable":14.0000000000000},
{"warehouseCode":"CA-1-US","quantityAvailable":4.0000000000000},
{"warehouseCode":"AB-1-CA","quantityAvailable":1.0000000000000},
{"warehouseCode":"WA-1-US","quantityAvailable":0.0000000000000},
{"warehouseCode":"PO-1-CA","quantityAvailable":0.0000000000000}
]
}
]"""
# converting the json string to a Python data structure
inventory = json.loads(JSON_DATA)
# representation in Python
#[{'inventory': [{'quantityAvailable': 0.0, 'warehouseCode': 'UT-1-US'},
#{'quantityAvailable': 0.0, 'warehouseCode': 'KY-1-US'},
#{'quantityAvailable': 14.0, 'warehouseCode': 'TX-1-US'},
#{'quantityAvailable': 4.0, 'warehouseCode': 'CA-1-US'},
#{'quantityAvailable': 1.0, 'warehouseCode': 'AB-1-CA'},
#{'quantityAvailable': 0.0, 'warehouseCode': 'WA-1-US'},
#{'quantityAvailable': 0.0, 'warehouseCode': 'PO-1-CA'}],
#'itemNumber': '75-5044'}]
# the interesting part
for items in inventory:
# get the elements in from the list
# the elements are dicts, in this case exactly one dict
print('itemNumber:', i['itemNumber'])
# nested loop iterating over the values of the key 'inventory'
for item in items['inventory']:
# the value is dict
code, qty = item['warehouseCode'],item['quantityAvailable']
print('warehouseCode:', code, 'quantityAvailable', qty)
# Output
#itemNumber: 75-5044
#warehouseCode: UT-1-US quantityAvailable 0.0
#warehouseCode: KY-1-US quantityAvailable 0.0
#warehouseCode: TX-1-US quantityAvailable 14.0
#warehouseCode: CA-1-US quantityAvailable 4.0
#warehouseCode: AB-1-CA quantityAvailable 1.0
