Poem Hindi 
कभी सपनों मे अपनों के सपनों को जरा सहेजना तो!
हो सकता है़!
कभी महसूस न किया तुमने होगा जो समझ आए वो!

यूँ बन वाचाल खुदा को बेवजह न तकलीफ़़ में डाल!
दे सकता है!
ये पुरे जमाने का दर्द; ज़रा समझ; न बन अतफ़ाल!

Just to understand where exactly you have to do the modification and what little mistake you did has already been pointed out in the above comments.

Solution to a list dict base problem, https://stackoverflow.com/questions/56814001/updating-json-fields-with-values-from-list (Unfortunately, the guy deleted the post)

Problem

In Python, list, dictionary are reference types. So if you will append the same dictionary to a list and if you will make any change to any of the dictionary, it will reflect in all other as well because all are pointing to the same memory location.

>>> l = [{"name": "Raghavendra Thakur", "age": 27}] * 4
>>> 
>>> l
[{'name': 'Raghavendra Thakur', 'age': 27}, {'name': 'Raghavendra Thakur', 'age': 27}, {'name': 'Raghavendra Thakur', 'age': 27}, {'name': 'Raghavendra Thakur', 'age': 27}]
>>> 
>>> l[0]
