将输出格式化为特定的 json

Question

I want to format JSON to the specific values. My final goal is to convert -33.494 143.2104 to {"lat":-33.494,"lon":143.2104}

I am converting IP to geo location latitude and longitude:

python3.5 -c "
import geoip2.database; reader=geoip2.database.Reader('/geoip_databases/GeoLite2-City.mmdb'); 
response = reader.city('1.2.3.4');
print (response.location.latitude, response.location.longitude)"

-33.494 143.2104

Tried to convert it to the desired output:

python3.5 -c "
import geoip2.database; reader=geoip2.database.Reader('/geoip_databases/GeoLite2-City.mmdb'); 
response = reader.city('1.2.3.4')
;a=(response.location.latitude, response.location.longitude); 
b=('{"lat":' + a + '}');
c=b.replace(' ',',"lon"'); 
print (c)"

Traceback (most recent call last):
  File "<string>", line 1, in <module>
TypeError: Can't convert 'tuple' object to str implicitly

How can I accomplish following output {"lat":-33.494,"lon":143.2104} still having one liner?

You can try with making a dict and doing a json.dumps soon after.

python3.5 -c "
import geoip2.database, json 
reader=geoip2.database.Reader('/geoip_databases/GeoLite2-City.mmdb'); 
response = reader.city('1.2.3.4');
loc_dict = { lat: response.location.latitude, lon: response.location.longitude }
print (json.dumps(loc_dict, indent=4))"
