Key Value Pair output

[buran]

the error is because you have extra opening bracket between dict and row.
if you need to get different json as body - construct the list of dicts

import json
rows = [(1, "Apple"), (2, "Banana"), (3, "Orange")]
json_rows = [dict(zip(('Id', 'Fruit'), (str(key), value))) for key, value in rows]
print(json.dumps(json_rows))

Output:
[{"Id": "1", "Fruit": "Apple"}, {"Id": "2", "Fruit": "Banana"}, {"Id": "3", "Fruit": "Orange"}]
