如何将数据框转换并保存为 csv python

Question

有没有办法像这样转换并保存以下数据帧到 csv 文件？

import requests
from bs4 import BeautifulSoup

url = 'https://ev-database.uk'
resp = requests.get(url)
soup = BeautifulSoup(resp.text, 'lxml')

urls = []
cars = []
for h in soup.find_all('h2'):
    a = h.find('a')
    cars.append(a.attrs['href'][10:])
    urls.append(a.attrs['href'])

import requests 
import pandas as pd

list_length = len(urls)
table = pd.DataFrame()

for x in range(5):
    page_link ='https://ev-database.uk' + urls[x]

    for i in range(1,3):
        next_table = pd.read_html(requests.get(page_link).content)[i]
        next_table[3] = cars[x]
        table = table.append(next_table, ignore_index = True)

数据框：

csv.output:

IIUC:

使用，

table.set_index([3,0])[1].unstack().rename_axis([None]).to_csv('csv.output')

输出：
