resolve typeerror: list indices must be integers or slices, not str

I am quite new to python, so maybe there is a simple answer to my question. I have imported data from a json file as follows:

input:
with open('file_destination.json', 'r', encoding='utf-8') as f:
    data = json.load(f)
print(data)

output: 
[{'Node': {'Construction': {'id': 'd9794e40-c894-5027-8576-b30a3eb3c95c'}]

I would like to be able to extract the data for e.g. id = d9794e40-c894-5027-8576-b30a3eb3c95c, however I get:

Traceback (most recent call last):
  File "main.py", line 11, in <module>
    print(data['id'])
TypeError: list indices must be integers or slices, not str

Can anyone help me resolve this issue?

I've run :

t=[{'Node': {'Construction': {'id': 'd9794e40-c894-5027-8576-b30a3eb3c95c'}}}]
print(t[0]['Node']['Construction']['id'])

And i get this output:

d9794e40-c894-5027-8576-b30a3eb3c95c

I assume this solves your problem.
