使用FOR循环遍历JSON对象

Question

我目前在一个数据分析新兵训练营，在6周的时间里，我收到了大量的信息。在python和juypter笔记本中工作。我在JSON对象上运行FOR循环时遇到了一些问题。特别希望从json中的每个不同的“full_name”中取出6个“padid”，并按顺序打印它们。我似乎就是不能让我那可怜疲惫的大脑去理解我需要什么语法才能让它运行。任何建议或见解都会非常有帮助！

import requests
import json

url = "https://api.spacexdata.com/v2/launchpads"

space = requests.get(url)

spacex= space.json()
spacex

Answer 1

spacex只是一个字典列表。您可以像遍历其他列表一样遍历它。

for site in spacex:
    print(site['full_name'])
