Is there an Object spread syntax in python 2.7x like in Javascript?

Question

How can I spread an objects/dict(?) properties and into a new object/dict?

Simple Javascript:

const obj = {x: '2', y: '1'} const thing = {...obj, x: '1'} // thing = {x: '1', y: 1} 

Python:

regions = [] for doc in locations_addresses['documents']:    regions.append(         {             **doc, # this will not work             'lat': '1234',             'lng': '1234',          }     ) return json.dumps({'regions': regions, 'offices': []})

If you had Python >=3.5, you can use key-word expansion in dict literal:

>>> d = {'x': '2', 'y': '1'} >>> {**d, 'x':1} {'x': 1, 'y': '1'} 

This is sometimes referred to as "splatting".

If you are on Python 2.7, well, there is no equivalent. That's the problem with using something that is over 7 years old. You'll have to do something like:

>>> d = {'x': '2', 'y': '1'} >>> x = {'x':1} >>> x.update(d) >>> x {'x': '2', 'y': '1'}
