如何从 json 输出中获取特定通用对象的所有数据值
how to get the all data values of a specific universal object from json output
- 我有这个货币转换器 api 网站，我已将其用于我的转换器模块。
- 我想通过从问题底部显示的 json 数据中提取数据来简化代码
我的代码：
import json
from urllib.request import urlopen
html = urlopen("https://free.currconv.com/api/v7/currencies?apiKey=<API KEY>")
data = json.load(html)
currencies = data['requests']
print(currencies)
- 输出显示
{ "requests" } 中的整个 JSON（如上链接）
- 我现在的问题：如何从所有 json 对象中获取 id 的数据值，如通配符值提取。

鉴于您的 data 对象
- 与
id 的 key-value 对在 data['results'] 之下
- 遍历每个
key（例如 'BTN'）和 value（{'currencyName': 'Bhutanese Ngultrum', 'id': 'BTN'}）以获得 id
- 每种货币的
key 也是 id
'BTN': {'currencyName': 'Bhutanese Ngultrum', 'id': 'BTN'}
使用pandas
- 这将为您提供所有数据，而不仅仅是
id
- 使用pandas.json_normalize & pandas.concat创建JSON数据的数据框。
pd.json_normalize(v) for v in data['results'].values() 为每个 {'currencyName': 'Albanian Lek', 'currencySymbol': 'Lek', 'id': 'ALL'}pd.concat(...) 将所有数据帧合并为一个数据帧。
import pandas as pd
# load all the currencies into the dataframe
df = pd.concat(pd.json_normalize(v) for v in data['results'].values()).reset_index(drop=True)
# display df
currencyName currencySymbol id
0 Albanian Lek Lek ALL
1 East Caribbean Dollar $ XCD
2 Euro € EUR
3 Barbadian Dollar $ BBD
4 Bhutanese Ngultrum NaN BTN
# save all the data to csv
df.to_csv('currencies.csv', index=False)
# get a list of id
ids = df.id.tolist()
没有pandas
- 如果您只想要所有
id 个值
- 以下代码将生成包含所有
id 值的列表。
ids = list()
for v in data['results'].values():
ids.append(v['id'])
# as a list-comprehension
ids = [v['id'] for v in data['results'].values()]

print(currencies)
- 输出显示
{ "requests" } 中的整个 JSON（如上链接）
- 我现在的问题：如何从所有 json 对象中获取 id 的数据值，如通配符值提取。

鉴于您的 data 对象
- 与
id的key-value对在data['results']之下- 遍历每个
key（例如'BTN'）和value（{'currencyName': 'Bhutanese Ngultrum', 'id': 'BTN'}）以获得id
- 遍历每个
- 每种货币的
key也是id'BTN': {'currencyName': 'Bhutanese Ngultrum', 'id': 'BTN'}
使用pandas
- 这将为您提供所有数据，而不仅仅是
id - 使用pandas.json_normalize & pandas.concat创建JSON数据的数据框。
pd.json_normalize(v) for v in data['results'].values()为每个{'currencyName': 'Albanian Lek', 'currencySymbol': 'Lek', 'id': 'ALL'} 创建一个数据框
pd.concat(...)将所有数据帧合并为一个数据帧。
import pandas as pd
# load all the currencies into the dataframe
df = pd.concat(pd.json_normalize(v) for v in data['results'].values()).reset_index(drop=True)
# display df
currencyName currencySymbol id
0 Albanian Lek Lek ALL
1 East Caribbean Dollar $ XCD
2 Euro € EUR
3 Barbadian Dollar $ BBD
4 Bhutanese Ngultrum NaN BTN
# save all the data to csv
df.to_csv('currencies.csv', index=False)
# get a list of id
ids = df.id.tolist()
没有pandas
- 如果您只想要所有
id个值 - 以下代码将生成包含所有
id值的列表。
ids = list()
for v in data['results'].values():
ids.append(v['id'])
# as a list-comprehension
ids = [v['id'] for v in data['results'].values()]
