SF OCAPI pagination loop - python-3.x

Question

I am trying to get a pagination loop inside of another loop where I query multiple environments in salesforce OCAPI. My code goes like this. I first declare some variables to use in the loop:
URLs=["it","at","lv","ee","lt"]
base_url = "https://example.net/s/-/dw/data/v22_4/customer_lists/"
start = 0
count = 200
Then I create the body for the requests:
body = """
{
"query": {
"bool_query": {
"must": [
{
"filtered_query": {
"query": {
"match_all_query": {}
},
"filter": {
"range_filter": {
"field": "creation_date",
"from": """ + start_time_formatted + """,
"to": """ + end_time_formatted + """
}
}
}
}
]
}
},
"expand":["primary_address"],
"select": "(**)",
"count": """ + str(count) + """,
"start": """ + str(start) + """
}"""
Based on these variables I create an initial For loop where I query multiple URL environments, I tried to input a while loop for pagination within the For loop but it doesn't give me the expected result. The code is below:
for country in URLs:
url = base_url + str(country) + "/customer_search"
response = requests.post(url, headers={'Content-Type': 'application/json','Accept': 'application/json','Authorization': 'Bearer ' + oauth_token}, data=body)
data = response.json()
while (start < total):
start = start * count
response = requests.post(url, headers={'Content-Type': 'application/json','Accept': 'application/json','Authorization': 'Bearer ' + oauth_token}, data=body)
data = response.json()
dataframe = pd.json_normalize(data['hits'], max_level=2)
dfs.append(dataframe)
df = pd.concat(dfs, ignore_index=True)
The json output that I usually get from the query looks similar to this(with records inside hits course):
{{'_v': '22.4',
'_type': 'customer_search_result',
'count': 200,
'expand': ['primary_address'],
'hits': [],
'next': {'_type': 'result_page', 'count': 200, 'start': 200},
'query': {'bool_query': {'_type': 'bool_query',
'must': [{'filtered_query': {'_type': 'filtered_query',
'filter': {'range_filter': {'_type': 'range_filter',
'field': 'creation_date',
'from': '2022-01-01T00:00:00.000Z',
'to': '2022-05-09T17:03:16.000Z'}},
'query': {'match_all_query': {'_type': 'match_all_query'}}}}]}},
'select': '(**)',
'start': 0,
'total': 650}
Now what I need is that the while loop increases the starting point with each iteration and collects all total records for each URL by then stopping in the end and give the results. Do you have any idea on how I can create this loop? count is 200 because that's the maximum amount of records I'm allowed to query with each call. Also count should then change based on total amount of records so for example if it goes in batches of 200 then for the last 150 count should change to 150 instead of 200.
