python - add a pair of key/value for each element of a list of dicts

Question

I have the following data structure:

db['data'][products']

Inside that, i have a list of dicts:

[{'name':'John', 'id':1},
 {'name':'Matt', 'id':2}]

How to add a fix pair of key/value for each element of list ?

Results should be something like that:

[{'name':'John', 'id':1, 'new_key':'new_value'},
 {'name':'Matt', 'id':2, 'new_key':'new_value'}]

Thanks

Answer 1

with list comprehension:

result = [dict(item, **{'new_key':'new_value'}) for item in db['data']['products']]
