将元组转换为字典中的列表

Question

I have a GeoJSON output in the form of:

{'type': 'Point', 'coordinates': (0.00027777777777777827, 22.000138888888873)}

How can I convert the value of 'coordinates' from a tuple to a list while keeping 'type' as is?

I've tried using {k: [list(ti) for ti in v] for k, v in geom.items()} as given here where geom = geometry.mapping(geometry.Point(x, y)) but it doesn't help.

I see an error that says 'Float object is not iterable'

I'm using the shapely library

Answer 1

You can only change the 'coordinates' key as a list:

geom['coordinates'] = list(geom['coordinates'])

OUTPUT :

{'type': 'Point', 'coordinates': [0.00027777777777777827, 22.000138888888873]}

Answer 2

You can convert directly as follows:

a['coordinates'] = list(a['coordinates'])

where a is your dict.

Answer 3

Very simple way, testing it via Python console:

>>> d = {'type': 'Point', 'coordinates': (0.00027777777777777827, 22.000138888888873)}
>>>
>>> type(d)
<class 'dict'>
>>>
>>> d['coordinates']
(0.00027777777777777827, 22.000138888888873)
>>>
>>> type(d['coordinates'])
<class 'tuple'>
>>>
>>> list(d['coordinates'])
[0.00027777777777777827, 22.000138888888873]

Finally, you only overwrite the contents of the dictionary:

>>> d['coordinates'] = list(d['coordinates'])
