Splitting dict by value of one of the keys

Question

I\'ve got a dictionary with data of the same length (but different types), something like:

data = {
    \"id\": [1,1,2,2,1,2,1,2], 
    \"info\": [\"info1\",         


        

Answer 1

with comprehension lists :

data1 = [ data["info"][idx] for idx, x in enumerate(data["id"]) if x == 1 ]
#data1 = ['info1', 'info2', 'info5', 'info7']

If you want to recover all the keys :

data1 = [ { key : data[key][idx] for key in data.keys() }  for idx, x in enu
merate(data["id"]) if x == 1 ]
>>> data1
[{'info': 'info1', 'id': 1, 'number': 1}, {'info': 'info2', 'id': 1, 'number': 2
}, {'info': 'info5', 'id': 1, 'number': 5}, {'info': 'info7', 'id': 1, 'number':
 7}]
