问题

我想获取来自这个网站的8年数据(图表'Encours des parts référencées')。我不知道如何找到这些数据。我检查了网站,但没有看到它们。我想知道它们在哪里,如何获取它们以及应该使用什么API?

这是网站的图片

我尝试了以下代码:

import requests
import pandas as pd
from bs4 import BeautifulSoup
import json

但之后我不知道该怎么做。

任何帮助都将有助于我。

数据以Json形式存储在页面中。要提取到pandas数据帧,您可以执行以下操作:

import json
import requests
import pandas as pd
from bs4 import BeautifulSoup

url = "https://www.quantalys.com/espace/518"

soup = BeautifulSoup(requests.get(url).content, "html.parser")
data = soup.select_one("#chartEncours8a input")["value"]
data = json.loads(data)

df = pd.DataFrame(data['dataProvider'])
df['unit'] = data['valueAxes'][0]['unit']
print(df)

打印输出:

   category  column-1   unit
0      2015     41.02   Mrd€
1      2016     44.92   Mrd€
2      2017     43.44   Mrd€
3      2018     31.58   Mrd€
4      2019     25.30   Mrd€
5      2020     25.26   Mrd€
6      2021     25.55   Mrd€
7      2022     19.57   Mrd€
英文:

The data is stored in the page in Json form. To extract it to pandas dataframe you can do:

import json
import requests
import pandas as pd
from bs4 import BeautifulSoup

url = "https://www.quantalys.com/espace/518"

soup = BeautifulSoup(requests.get(url).content, "html.parser")
data = soup.select_one("#chartEncours8a input")["value"]
data = json.loads(data)

df = pd.DataFrame(data['dataProvider'])
df['unit'] = data['valueAxes'][0]['unit']
print(df)

Prints:

   category  column-1   unit
0      2015     41.02   Mrd€
1      2016     44.92   Mrd€
2      2017     43.44   Mrd€
3      2018     31.58   Mrd€
4      2019     25.30   Mrd€
5      2020     25.26   Mrd€
6      2021     25.55   Mrd€
7      2022     19.57   Mrd€
