Mutilple JSON root element errors - json

Question

The file I am calling is JSON with padding and I have done my simple coding to remove the padding but it appears by stringing together multiple JSON strings the formatting is not correct and I get root element errors.
I am using the output of the python program and running it through an online JSON formatter and validator website to check my output. I am a learner so please bear with my inexperience. All help appreciated.
import json
import re
import requests
payload = {}
headers = {}
for race in range(1, 3):
url = f"https://s3-ap-southeast-2.amazonaws.com/racevic.static/2018-01-01/flemington/sectionaltimes/race-{race}.json?callback=sectionaltimes_callback"
response = requests.request("GET", url, headers=headers, data=payload)
strip = 'sectionaltimes_callback'
string = response.text
repl =''
result = re.sub(strip, repl, string)
print(result)

Answer 1

This is one way of obtaining the data you're looking for:
import requests
import json
import pandas as pd
headers = {'User-Agent' : 'Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:103.0) Gecko/20100101 Firefox/103.0',
'Accept-Language' : 'en-US,en;q=0.5'}
for race in range(1, 3):
url = f"https://s3-ap-southeast-2.amazonaws.com/racevic.static/2018-01-01/flemington/sectionaltimes/race-{race}.json?callback=sectionaltimes_callback"
r = requests.get(url, headers=headers)
json_obj = json.loads(r.text.split('sectionaltimes_callback(')[1].rsplit(')', 1)[0])
df = pd.DataFrame(json_obj['Horses'])
print(df)
This would return (print out in terminal) a dataframe for each race:
