这段代码使用Python编程语言编写，主要用到了tkinter、pdfkit、BeautifulSoup和requests等库。代码目的是将指定网页转换为PDF文件并保存在本地。通过获取网页标题作为文件名，生成PDF文件。其中包括了“enable-local-file-access”参数，用于允许访问本地文件。具体实现方式是先通过requests库获取网页内容，再利用BeautifulSoup库对网页内容进行解析，提取网页标题。最后利用pdfkit库生成和保存PDF文件。该段代码的网页链接是http://funds.hexun.com/2020-07-28/201774800.html。

# 导入必要的模块

from bs4 import BeautifulSoup

# 定义一个函数，用于扫描网页并输出链接
def scan():
# 获取用户输入的网址
url = entry.get()
# 发送请求并获取响应内容
res = requests.get(url)
# 使用 BeautifulSoup 解析响应内容
soup = BeautifulSoup(res.text, 'html.parser')
# 查找所有的链接标签
links = soup.find_all('a')
# 遍历所有的链接标签并输出链接
for link in links:
print(link.get('href'))

# 创建一个窗口对象
root = tk.Tk()
# 设置窗口标题
root.title('Web Scanner')

# 创建一个标签对象并添加到窗口中
label = tk.Label(root, text='Enter URL:')
label.pack()
