Download .vsix extension files from Visual Studio Marketplace using python

Create extensions.txt file in script location and write list of extensions to get inside it. For example:

ms-toolsai.jupyter
ms-python.vscode-pylance
ms-vscode.cpptools
# and so on

This is the script:

import requests
from time import sleep
from os.path import exists
extensions = []
with open("extensions.txt", 'r') as f:
   for line in f:
      if not line.startswith('#'):
         extensions.append(line.strip())
with requests.session() as session:
   session.headers.update({

      "host": "marketplace.visualstudio.com",

      "accept-language": "en-US,en;q=0.5",

      "Sec-Fetch-User": "?1",
      "Sec-GPC": "1"
   })
   session.get("https://marketplace.visualstudio.com/")
   for extension in extensions:
      pub, name = extension.split('.')
      if exists(f"{pub}.{name}.vsix"):
         print(f"'{name}'' already exists, skipping")
         continue
      print(f"Getting '{name}'")
      data = b''
      try:
         with session.get(f"https://marketplace.visualstudio.com/_apis/public/gallery/publishers/{pub}/vsextensions/{name}/latest/vspackage", stream=True) as stream:
            file_size = int(stream.headers["Content-Length"])
            for content in stream.iter_content(1024, decode_unicode=False):
               if content:
                  data += content
                  print(f"got {min(len(data)/file_size*100, 100):.2f}%", end='\r')
         print()
      except KeyboardInterrupt:
         print("\nExiting")
         quit()
      except Exception:
         print(f"Error for '{name}'")
         continue
      with open(f"{pub}.{name}.vsix", 'wb') as f:
         f.write(data)
      print("Done, waiting a bit before next request")
      sleep(5)
