I am new to python and i am working with some geojson files that contain a multiple objects each object represents a precinct. I need to print the coordinates for all of the precints how can i do this? i was trying this but it does not work:

import json

with open('districts and precinc data merged.json') as f:

    data = json.load(f)

for i in json['features']:

  print(i['geometry']['coordinates'])

this is an example of the json file:

    {"type":"FeatureCollection", "features": [

{"type":"Feature","geometry":{"type":"Polygon","coordinates":[[[552346.2856999999,380222.8998000007]]]]},"properties":{"OBJECTID":1,"STFID":"55001442500001","NAME":"0001"}},

{"type":"Feature","geometry":{"type":"Polygon","coordinates":[[[529754.7249999996,409135.9135999996],[529740.0305000003,408420.03810000047]]]},"properties":{"OBJECTID":2,"STFID":"55001537250001","NAME":"0001","COUSUBFP":"53725"}},

{"type":"Feature","geometry":{"type":"Polygon","coordinates":[[[508795.9363000002,441655.3672000002],[508813.49899999984,441181.034]]]},"properties":{"OBJECTID":6278,"STFID":"55141885750001","NAME":"0001","COUSUBFP":"88575"}}

]}

my desired output would be a for each line have the cordinates for each object like so:

[552346.2856999999,380222.8998000007]

[529754.7249999996,409135.9135999996],[529740.0305000003,408420.03810000047]

[508795.9363000002,441655.3672000002],[508813.49899999984,441181.034]

thank you for your help!

You have an error in your json. In first line you have 3 list open [[[ but closing 4 ]]]]. In your json file, replace [[[552346.2856999999,380222.8998000007]]]] with [[[552346.2856999999,380222.8998000007]]].

Then you can use nested loop,

x =  {"type":"FeatureCollection", "features": [

{"type":"Feature","geometry":{"type":"Polygon","coordinates":[[[552346.2856999999,380222.8998000007]]]},"properties":{"OBJECTID":1,"STFID":"55001442500001","NAME":"0001"}},

{"type":"Feature","geometry":{"type":"Polygon","coordinates":[[[529754.7249999996,409135.9135999996],[529740.0305000003,408420.03810000047]]]},"properties":{"OBJECTID":2,"STFID":"55001537250001","NAME":"0001","COUSUBFP":"53725"}},

{"type":"Feature","geometry":{"type":"Polygon","coordinates":[[[508795.9363000002,441655.3672000002],[508813.49899999984,441181.034]]]},"properties":{"OBJECTID":6278,"STFID":"55141885750001","NAME":"0001","COUSUBFP":"88575"}}

for i in x["features"]:

    for j in i["geometry"]["coordinates"][0]:

        print(j, end=",") # replace `n` with `,`

    print("b") # removes trailing , 



# output,
