Sort list of dictionaries by another list

Question

Sort list of dictionaries by another list. I have got list with dictionaries (IN) and I want to sort this by another list (sortValue).

Answer 1

You can also use the key parameter of the sorted function. In your case, you want the index of sortValue for the id of each item on the list:

>>> pprint(sorted(IN,key=lambda x:sortValue.index(x['id'])))
[{'id': 'b', 'val': 'Value', 'val1': 'Value1'},
 {'id': 'c', 'val': 'Value', 'val1': 'Value1'},
 {'id': 'a', 'val': 'Value', 'val1': 'Value1'}]
