如何沿 CSV 文件中的列寫入數據？

Question

當我寫入 csv 文件時，我的所有數據僅打印在第一列中。 使用我的循環，我如何遍歷列來寫入數據？

import csv
import bs4
import urllib
from urllib.request import  urlopen as uReq
from urllib.request import Request, urlopen
from bs4 import BeautifulSoup as soup

#For sites that can't be opened due to Urllib blocker, use a Mozilla User agent to get access
pageRequest = Request('https://coronavirusbellcurve.com/', headers = {'User-Agent': 'Mozilla/5.0'})
htmlPage = urlopen(pageRequest).read()
page_soup = soup(htmlPage, 'html.parser')
specificDiv = page_soup.find("div", {"class": "table-responsive-xl"})

TbodyStats = specificDiv.table.tbody.tr.contents
TbodyDates = specificDiv.table.thead.tr.contents


with open('CovidHTML.csv','w', newline= '') as file:
    theWriter = csv.writer(file)             
    theWriter.writerow(['5/4', ' 5/5', ' 5/6',' 5/7',' 5/8',' 5/9'])
    for i in range(3,len(TbodyStats)):
        if i%2 != 0:
            theWriter.writerow([TbodyStats[i].text])

另一種方法，僅供參考。

from simplified_scrapy import SimplifiedDoc,utils,req
html = req.get('https://coronavirusbellcurve.com/')
doc = SimplifiedDoc(html)
specificDiv = doc.select('div.table-responsive-xl') # Get first div. If you want to get all divs, use this method: doc.selects('div.table-responsive-xl')
# TbodyStats = specificDiv.tbody.trs.selects('td|th').text # Get data
# TbodyDates = specificDiv.thead.trs.selects('td|th').text # Get date
data = specificDiv.table.trs.selects('td|th').text # Get all
rows = []
for row in data:
    rows.append(row[1:])
utils.save2csv('test.csv',rows)

結果：

5/5,5/6,5/7,5/8,5/9
1213260,1237960,1266822,1294664,1314610
24423,24700,28862,27842,19946
2.05%,2.04%,2.33%,2.20%,1.54%

Answer 2

我認為您可以做到這一點（我無法確定測試，因為我手頭沒有您的確切數據）：

row = []
for i in range(3, len(TbodyStats), 2):
    row.append(TbodyStats[i].text)
    if len(row) == 6:
        theWriter.writerow(row)
        row = []

我將“步驟”添加到您的范圍內，因此您不必使用 % 來查找奇數索引，然后只構建每一行直到它達到 6 個成員，然后將其刷新到 csv 文件，然后清空該行以便您可以重復這個過程。
