您将需要Selenium，因为wesbite使用javascript来显示价格。 要使用Selenium选择产品的价格，您将需要类似：

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

driver.get('https://www.paodeacucar.com/produto/67746/')
print(WebDriverWait(driver, 20).until(EC.visibility_of_element_located((By.XPATH, "//schema[@itemprop='price']"))).get_attribute("content"))
