要批量查詢快遞單號，可以使用Python的第三方庫requests和BeautifulSoup。首先需要安裝這兩個庫：

pip install requests beautifulsoup4

然后使用以下代碼進(jìn)行批量查詢：

import requests
from bs4 import BeautifulSoup

def get_packages(url, packages):
    result = []
    for package in packages:
        headers = {
            'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/58.0.3029.110 Safari/537.3'}
        response = requests.get(url + '/' + package['package_id'], headers=headers)
        soup = BeautifulSoup(response.text, 'html.parser')
        print('查詢結(jié)果：', soup.prettify())
        result.append(soup)
    return result

if __name__ == '__main__':
    url = 'https://www.example.com/api/packets'  # 替換為實際的API地址
    package_ids = [
        '123456',
        '789012',
        '345678',
    ]
    packages = [{'package_id': package_id} for package_id in package_ids]
    result = get_packages(url, packages)
    for i, package in enumerate(result):
        print(f'第{i+1}個包裹：')
        print(package)

請將url變量替換為實際的API地址，將package_ids列表中的值替換為實際的快遞單號。運行此代碼后，它將輸出每個包裹的查詢結(jié)果。
