I have a dataset:
city_names_lst =
[{"cities":
{"city":
{"name":"New York",
"population": "18mln",
"suburbs":
{"s_name": "Brooklyn",
"population":"9mln"},
{"s_name": "Queens",
"population": "9mln"}}},
{"city":
{"name":"Washington DC",
"population":"10mln",
"suburbs":
{"s_name": "Maryland",
"population": "5mln"},
{"s_name": "Northern Virginia",
"population":"5mln"}}},
...}]
I need to iterate through the entire list and access the "name" key.
The code I have is:
city_names = []
for x in city_names_list:
city_names = x['city']['name']
However, it only fetches the first city name. How do I get all of them?
You were close. Append to the list, rather than reassigning its name:
city_names = []
for x in city_names_list:
city_names.append(x['city']['name'])
I'm assuming your data is not really all nested behind a "cities" key, like it is in the example dataset.
