尝试更改选择器：

import requests
from bs4 import BeautifulSoup

URL = "https://www.amazon.com/dp/B075CYMYK6?ref_=cm_sw_r_cp_ud_ct_FM9M699VKHTT47YD50Q6&th=1"
header = {
    "User-Agent": "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/118.0.0.0 Safari/537.36 Edg/118.0.2088.24",
    "Accept-Language": "en-US,en;q=0.9",
}

responce = requests.get(URL, headers=header)
soup = BeautifulSoup(responce.content, "lxml")

price = soup.find(class_="a-offscreen").get_text()
print(price)

打印：

$98.07
