import requests
from bs4 import BeautifulSoup
result = requests.get(f"https://www.indeed.com/jobs?q=web development&start=0")
source = result.content
soup = BeautifulSoup(source, "lxml")
job_posted = soup.find("div", {"id": "searchCountPages"}).text.strip()
job_posted = job_posted[10:-5].replace(",", "")
job_posted = int(job_posted)
print(job_posted)
從網站上抓取字串后，我嘗試將字串轉換為整數，當我運行該程式時，有時它可以作業，而其他時候卻不行！我收到此錯誤：ValueError: int() 的無效文字，基數為 10: 's | ' 第 1 頁
這是我想報廢的黃色
uj5u.com熱心網友回復：
如前所述，正則運算式在這里是合適的：
import re
p = re.compile(r"Page (\d*) of (\d*) jobs")
job_posted = soup.find("div", {"id": "searchCountPages"}).text.strip().replace(",", "")
page_num, page_count = map(int, p.match(job_posted).groups())
請注意，如果找不到確切的模式，這將出錯。
輸出：
In [3]: page_num, page_count = map(int, p.match(job_posted).groups())
In [4]: page_num
Out[4]: 1
In [5]: page_count
Out[5]: 96575
