How do you convert the code below into a List Comprehension? I'm confused about how to clear one of the lists during the iteration. I've seen how to do it before but I don't remember what it's called. Let alone what you call clearing a list during iteration (if there's a name for it).

```
data = [{"meal":"tacos","numbers":["0","1","2","3","4","5"]},{"meal":"pizza","numbers":["0","1","2","3","4","5"]}]

node_01 = []
for i in data:
    node_02 = []
    for x in i["numbers"]:
        node_02.append({"meal":i["meal"], "number":x})
    node_01.append({"master_list":"ML", "new_data":node_02})

```

Output:

```
[{'master_list': 'ML',
  'new_data': [{'meal': 'tacos', 'number': '0'},
   {'meal': 'tacos', 'number': '1'},
   {'meal': 'tacos', 'number': '2'},
   {'meal': 'tacos', 'number': '3'},
   {'meal': 'tacos', 'number': '4'},
   {'meal': 'tacos', 'number': '5'}]},
 {'master_list': 'ML',
  'new_data': [{'meal': 'pizza', 'number': '0'},
   {'meal': 'pizza', 'number': '1'},
   {'meal': 'pizza', 'number': '2'},
   {'meal': 'pizza', 'number': '3'},
   {'meal': 'pizza', 'number': '4'},
   {'meal': 'pizza', 'number': '5'}]}]

```
