Question

What is a pythonic way to remap each dictionary key in a list of identically-keyed dictionaries to different key names? E.g.,

[{'type_id': 6, 'type_name': 'Type 1'}, {'type_id': 12, 'type_name': 'Type 2'}] 

must transform into

[{'type': 6, 'name': 'Type 1'}, {'type': 12, 'name': 'Type 2'}]

(I need to do the transformation in order to match an output specification for an API I’m working on.)

Answer 1

just use a list comprehension

>>> d = [{'type_id': 6, 'type_name': 'Type 1'}, {'type_id': 12, 'type_name': 'Type 2'}]
>>> print [{'type':x['type_id'],'name':x['type_name']} for x in d]
[{'type': 6, 'name': 'Type 1'}, {'type': 12, 'name': 'Type 2'}]
>>>
