將輸出格式化為特定的 json

Question

我想將 JSON 格式化為特定值。 我的最終目標是將-33.494 143.2104轉換為{"lat":-33.494,"lon":143.2104}

我正在將 IP 轉換為地理位置緯度和經度：

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

試圖將其轉換為所需的輸出：

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

如何完成以下輸出 {"lat":-33.494,"lon":143.2104} 仍然有一個班輪？

您可以嘗試制作一個dict並在不久之后做一個json.dumps 。

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))"
