抱歉，我對編碼不熟悉，但我真的很想學習。我無法傳遞我想要的值，在這種情況下，這只是我想從網(wǎng)絡上抓取的數(shù)字。問題是我無法將我用 beautifulsoup 抓取的值傳遞到 csv 文件，任何好心人可以幫助我嗎？from bs4 import BeautifulSoupfrom urllib.request import Request, urlopenimport csvreq = Request('https://www.infodolar.com.mx/tipo-de-cambio-dof-diario-oficial-de-la-federacion.aspx', headers={'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/86.0.4240.75 Safari/537.36'})html_page = urlopen(req).read()soup = BeautifulSoup(html_page,'html.parser')Dollar = soup.find('td','colCompraVenta')print (Dollar.text)file=open('New.csv', 'wb')writer = csv.writer(file)writer.writerows([Dollar.encode('utf-8')])file.close()

將此行更改為file=open('New.csv', 'wb')您file=open('New.csv', 'w') 的代碼將如下所示
from bs4 import BeautifulSoup
from urllib.request import Request, urlopen
import csv
req = Request('https://www.infodolar.com.mx/tipo-de-cambio-dof-diario-oficial-de-la-federacion.aspx', headers={'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/86.0.4240.75 Safari/537.36'})
html_page = urlopen(req).read()
soup = BeautifulSoup(html_page,'html.parser')
Dollar = soup.find('td','colCompraVenta')
print (Dollar.text)
file=open('New.csv', 'w')
writer = csv.writer(file)
writer.writerows([Dollar.encode('utf-8')])
file.close()
