我用python与硒结合编写了一个脚本,以解析网页中的某些动态内容,并将其相应地写入csv文件。除了 the date 以外,以下脚本可以无错误地执行此操作。

如果查看该站点的内容,可以看到该表格数据中没有提到年份。

但是,当我单击输出文件中Date列标题下的任何单元格时,默认情况下excel将其计为当前年份,而the date应该是2004。如何根据下图2中显示的内容来定年2004

我正在尝试的脚本:

import csv
import datetime
from selenium import webdriver
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC

url = "http://info.nowgoal.com/en/League/2004-2005/36.html"

def get_information(driver,link):
    driver.get(link)
    for items in wait.until(EC.visibility_of_all_elements_located((By.CSS_SELECTOR,'table#Table3 tr')))[2:]:
        try:
            date = items.find_elements_by_css_selector("td")[1].text.split("\n")[0]
            date = datetime.datetime.strptime(date, '%m-%d').strftime('%d-%B')
        except Exception: date = ""
        try:
            match_name = items.find_elements_by_css_selector("td")[2].find_element_by_tag_name("a").text
        except Exception: match_name = ""
        writer.writerow([date,match_name])
        print(date,match_name)

if __name__ == '__main__':
    driver = webdriver.Chrome()
    wait = WebDriverWait(driver,10)
    with open("outputfile.csv","w",newline="") as infile:
        writer = csv.writer(infile)
        writer.writerow(['Date','Match name'])
        try:
            get_information(driver,url)
        finally:  
            driver.quit()

这是在csv文件中显示日期的方式: enter image description here

您可以按如下所示将正确的年份添加到单元格:

import datetime

date = "05-15"
date = datetime.datetime.strptime(date, '%m-%d').replace(year=2004).strftime('%d-%B-%Y')

print(date)

这将显示:

15-May-2004
