I only get the last nested item for city,state,country, BUT I want to print all the cities, states and countries of each event in the same line.

CodePudding user response：
Because in your location there is more than one location.
That is why city, state, country gets last one.
Look you set city = firstCity and then you set city = secondCity. Here your location for loop sets last value to variables. And you print it outside of location loop.
just print it in location loop or do something similar to my code.
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)
and here is output:
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
Here if you print inside of location loop:
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)
your output would be:
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
if you don't want to repeat printed locations. Just do something similar to my first example

Does this work for you?
EDIT - BTW, your problem is you are reassigning variables with each iteration of city and country, you need to add them to the variable eg city = " " location.get('city', '')
from json import loads as json_loads
from re import sub as re_sub
data = json_loads(open('json.json').read())
for event in data['input']:
output = " · ".join([i for i in event.values() if type(i) != list])
for location in event['location']:
output = " · " ", ".join([i for i in location.values()])
output = re_sub(r"(\d) · (\d)", r"\1 / \2", output)
print(output)
output:
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
