from lxml import etree
# 图片地址:
url = 'https://sc.chinaz.com/tupian/meinvxiezhen.html'

headers = {

}

# 发送请求获取响应
res = requests.get(url=url, headers=headers)

html = etree.HTML(res.text)

# 图片和地址的xpath
title = html.xpath('//div[@id="container"]/div[*]/div/a/img/@alt')
img_url = html.xpath('//*[@id="container"]/div[*]/div/a/img/@alt')
# print(title)
for i in title:
    i2 = 'http:' + i

# 标题xpath     //*[@id="container"]/div[*]/div/a/img/@alt
# 地址xpath     //*[@id="container"]/div[*]/div/a/img/@src

我运行了你的代码，并没有打印不出来的问题，只是打印出来的是乱码，在获取到响应后更改字符编码为 utf-8即可正常显示。

...
# 发送请求获取响应
res = requests.get(url=url, headers=headers)
res.encoding = 'utf-8'
html = etree.HTML(res.text)
...
