从字典返回值的有序子集

Question

我有这本字典

people = {'people': [{'name': 'Christina Koch', 'craft': 'ISS'}, {'name': 'Alexander Skvortsov', 'craft': 'ISS'}, {'name': 'Luca Parmitano', 'craft': 'ISS'}, {'name': 'Andrew Morgan', 'craft': 'ISS'}, {'name': 'Oleg Skripochka', 'craft': 'ISS'}, {'name': 'Jessica Meir', 'craft': 'ISS'}], 'number': 6, 'message': 'success'}

我只需要知道名字，比如：

    Alexander Skvortsov
    Alexey Ovchinin
    Andrew Morgan
    Christina Koch
    Luca Parmitano
    Nick Hague

谢谢你的帮助

Answer 1

这应该管用。你知道吗

d = {'people': [{'name': 'Christina Koch', 'craft': 'ISS'}, {'name': 'Alexander Skvortsov', 'craft': 'ISS'}, {'name': 'Luca Parmitano', 'craft': 'ISS'}, {'name': 'Andrew Morgan', 'craft': 'ISS'}, {'name': 'Oleg Skripochka', 'craft': 'ISS'}, {'name': 'Jessica Meir', 'craft': 'ISS'}], 'number': 6, 'message': 'success'}

for name in sorted([person['name'] for person in d['people']]):
  print(name)

Answer 2

可以这样做：

d = {'people': [{'name': 'Christina Koch', 'craft': 'ISS'}, {'name': 'Alexander Skvortsov', 'craft': 'ISS'}, {'name': 'Luca Parmitano', 'craft': 'ISS'}, {'name': 'Andrew Morgan', 'craft': 'ISS'}, {'name': 'Oleg Skripochka', 'craft': 'ISS'}, {'name': 'Jessica Meir', 'craft': 'ISS'}], 'number': 6, 'message': 'success'}

for p in d['people']:
    print(p['name'])

或者，如果您想将结果列在一个列表中，请按字母顺序排序：

name_list = sorted([p['name'] for p in d['people']])
