¿Cómo puedo imprimir TODOS mis datos json anidados al final de cada línea "padre" en python?

import json
with open('json.json') as f:
 data = json.load(f)
for event in data['input']:
 edition = event.get('edition', '')
 name = event['name']
 start_date = event['startDate']
 end_date = event.get('endDate', '')
 for location in event['location']:
 city= location.get('city', '')
 state= location.get('state', '')
 country= location.get('country', '')
 
 
 print(edition,name,start_date,end_date,city,state,country)
---
{
 "input": [
 {
 "edition": "4th",

 {
  "city": "Barcelona",
  "country": "Spain"
 }
 ]
 },
 {
 "edition": "3rd",

 "endDate": "2016-05-20",
 "location": [
 {

 },

 }
 ]
 },
 {

 "name": "Product Owner Rule Book",
 "startDate": "2016-04-11",
 "endDate": "2016-04-13",
 "location": [
 {

 "country": "Spain"
 }
 ]
 },
 {

}

Solo obtengo el último elemento anidado para ciudad, estado, país, PERO quiero imprimir todas las ciudades, estados y países de cada evento en la misma línea.

Solución del problema

Porque en tu ubicación hay más de una ubicación. Es por eso que la ciudad, el estado y el país quedan en último lugar. Mira, te pones city = firstCityy luego te pones city = secondCity. Aquí su ubicación for loopestablece el último valor para las variables. Y lo imprimes fuera del bucle de ubicación. simplemente imprímalo en el bucle de ubicación o haga algo similar a mi código.

for event in data['input']:
 edition = event.get('edition', '')
 name = event['name']
 start_date = event['startDate']
 end_date = event.get('endDate', '')
 loc = ''
 for location in event['location']:
 city = location.get('city', '')
 state = location.get('state', '')
 country = location.get('country', '')
 if city:
 loc += city
 if state:
 loc += ' | ' + state
 if country:
 loc += ' | ' + country
 if location!= event['location'][-1]:
 loc += ', '
 print(edition, name, start_date, end_date, loc)

y aquí está la salida:

4th JBCN Conference 2018-06-11 2018-06-13 Barcelona | Spain
3rd DevTernity 2018-11-30 2018-12-01 Riga | Latvia
1st I T.A.K.E Unconference 2016-05-19 2016-05-20 Bucharest | Romania, Maramures | Romania
2nd Product Owner Rule Book 2016-04-11 2016-04-13 Paris | France, Madrid | Spain
 Upfront Summit 2018-02-01 Los Angeles | California | United States
 IBM Think 2018-03-19 | Nevada | United States

Aquí, si imprime dentro del bucle de ubicación:

for event in data['input']:
 edition = event.get('edition', '')
 name = event['name']
 start_date = event['startDate']
 end_date = event.get('endDate', '')
 for location in event['location']:
 city = location.get('city', '')
 state = location.get('state', '')
 country = location.get('country', '')
 print(edition, name, start_date, end_date, city, state, country)

su salida sería:

4th JBCN Conference 2018-06-11 2018-06-13 Barcelona Spain
3rd DevTernity 2018-11-30 2018-12-01 Riga Latvia
1st I T.A.K.E Unconference 2016-05-19 2016-05-20 Bucharest Romania
1st I T.A.K.E Unconference 2016-05-19 2016-05-20 Maramures Romania
2nd Product Owner Rule Book 2016-04-11 2016-04-13 Paris France
2nd Product Owner Rule Book 2016-04-11 2016-04-13 Madrid Spain
 Upfront Summit 2018-02-01 Los Angeles California United States
 IBM Think 2018-03-19 Nevada United States

si no desea repetir las ubicaciones impresas. Solo haz algo similar a mi primer ejemplo.
