An error in the parser code for VK, am I doing something wrong?

Question

Python

Roughly speaking, it checks whether there is such a VK ID or not, for example:
durov - busy ID
Anna - Borrow ID
12 - Free ID Error 404 page not found
Roughly speaking, load the list into a column of 1000+ id and believe there is such an ID or not?
So that I could pick up a short, unoccupied letter ID Well, you understand me.
If there is a free ID from the list of my ID, then it writes to the file, if not, then it’s bad)

Here is the code, sorry, that without tabulation, the essence of the checker parser is as follows:

import requests 

file = open('urls.txt', 'r') 
not_found = open('not_found.txt', 'w') 
found = open('found.txt', 'w') 
for line in file: 
id = line.split('\n')[0] 
if id.isdigit(): 
text = requests.get('https://vk.com/id'+id).text 
else: 
text = requests.get('https://vk.com/'+id).text 
if '<title>404 Not Found</title>' in text: 
print('Not found: '+id) 
not_found.write(id+'\n') 
not_found.flush() 
else: 
print('Found: '+id) 
found.write(id+'\n') 
found.flush() 

found.close() 
not_found.close() 
file.close()

Answer 1

You should pay attention to the py-vkontakte library , which allows you to work with the vk.com API.

def get_user_not_found(users):
  for user in users:
    try:
      api.get_user(user)
    except vk.error.VKError as err:
      if '113' == err.code:
        yield user

>>> ['asdf0aisdf', 'durov', 123]
>>> [user for user in get_user_not_found(users)]
['asdf0aisdf']

Answer 2

Isn't it better to do it through api VK?
