我需要立即废弃数据（5-10 秒），但我的代码可以运行 60-80 秒。
如果我有更好更快的想法，请告诉我。无论是使用 Selenium 还是其他语言都没关系。
这是我的代码：
from selenium import webdriver
from selenium.webdriver.common.by import By
import pandas as pd
import time
start = time.time()
driver = webdriver.Chrome()
driver.get("https://www.investing.com/economic-calendar/")
# Scrape the data
events = []
# Locate the rows in the table
rows = driver.find_elements(By.XPATH, '/html/body/div[6]/section/div[6]/table/tbody/tr[14]')
for row in rows:
try:
actual = row.find_element(By.XPATH, './td[5]').text
previous = row.find_element(By.XPATH, './td[7]').text
events.append([actual, previous])
except Exception as e:
print(f"Error processing row: {e}")
driver.quit()
df = pd.DataFrame(events, columns=[ 'Actual', 'Previous'])
df.head()
df.to_csv('economic_calendar.csv', index=False)
end = time.time()
print(end - start)
要快速获取数据，请不要使用
seleniumimport pandas as pd
import requests
from bs4 import BeautifulSoup
url = "https://www.investing.com/economic-calendar/"
soup = BeautifulSoup(requests.get(url).content, "html.parser")
table = soup.select_one("#economicCalendarData")
day = soup.select_one(".theDay").text
all_data = []
for row in table.select("tbody tr"):
tds = row.select("td")
if len(tds) != 8:
continue
all_data.append(
{
"Day": day,
"Time": tds[0].get_text(strip=True),
"Cur": tds[1].get_text(strip=True),
"Imp.": "*" * len(tds[2].select(".grayFullBullishIcon")),
"Event": tds[3].get_text(strip=True),
"Actual": tds[4].get_text(strip=True),
"Forecast": tds[5].get_text(strip=True),
"Previous": tds[6].get_text(strip=True),
}
)
df = pd.DataFrame(all_data)
print(df)
