I need to find a dict in this list based on a unique value (id) inside that dict:
[
{
'title': 'some value',
'value': 123.4,
'id': 'an id'
},
{
'title': 'another title',
'value': 567.8,
'id': 'another id'
}
]
Caveats: title and value can be any value (and the same), id would be unique.
I know this can be done through the use of loops, but this seems cumbersome
my_item = next((item for item in my_list if item['id'] == my_unique_id), None)
This iterates through the list until it finds the first item matching my_unique_id, then stops. It doesn't store any intermediate lists in memory (by using a generator expression) or require an explicit loop. It sets my_item to None of no object is found. It's approximately the same as
for item in my_list:
if item['id'] == my_unique_id:
my_item = item
break
else:
my_item = None
else clauses on for loops are used when the loop is not ended by a break statement.
