I had some problems with my Python code. My code:

import os
logininfo = list()
with open(os.getcwd() + '/login/info.txt', 'r') as f:
     logininfo = f.readlines()

But my code isn’t work, so how do I fix that?

Edit: I changed the quote and changed the ‘ to '

Problem 2: After I fix all that look like my computer is freeze now and I can’t even move my mouse. After freeze for a while, the code make my computer ran to BSOD. What happened?

Okay, I think I see what the problem in problem 2 that my file was too big with 50 GB of login information of my server. Thanks you guy for helping me solve the problem 1.

    what do you mean code isn't work, what is the resulting output, full text of Traceback error? That will likely show us all the source of the problem – chickity china chinese chicken Sep 27 '21 at 22:47

    why are you using two // ? – Andressa Cabistani Sep 27 '21 at 22:47
  • can you add more about the error? – Andressa Cabistani Sep 27 '21 at 22:48

    @Andressa Cabistani I believe thats the problem. – sur0k Sep 27 '21 at 22:48
  • Also the string for the `'r'` wasn't using single quotes, it was using this one: ` – Andressa Cabistani Sep 27 '21 at 22:52
  • if that `‘//login//info.txt’` is the same unicode characters in your code as posted, you should get `SyntaxError: invalid character in identifier` for the, `‘`, curly single quotes are unvalid unicode for python syntax. possibly replace those characters with `'`, `'//login//info.txt', 'r'` – chickity china chinese chicken Sep 27 '21 at 22:52

Your problem is likely that your / (forward slashes) are supposed to be \ (backslashes). It is also a good practice to use os.path.join() when concatenating file paths. Make sure login\info.txt does not have a backslash in front of it. I printed the list afterwards to make sure it was working. Windows file paths use \\.

import os
with open(os.path.join(os.getcwd(), 'login\info.txt'), 'r') as f:
    logininfo = f.readlines()
print(logininfo)

I believe the wrong thing is that you're using double slashs, when it should be:

import os

with open(os.getcwd() + ‘/login/info.txt’, 'r') as f:
     logininfo = f.readlines()

I reproduced the error here, created a file with the same folder structure as yours, and this definitely should work:

In [3]: with open(os.getcwd() + '/login/info.txt', 'r') as f:
   ...:     lines = f.readlines()
   ...:     for line in lines:
   ...:         print(line)
   ...: 
Olá,

Regardless of OS, I would recommend using pathlib module to deal with system paths and to decrease ambiguity in OS path handling. So, regardless of OS, an API would be (including your code):

from pathlib import Path

file_path = Path.cwd() / 'login' / 'info.txt'

with open(file_path, 'r') as f:
    login_info = f.readlines()

Get familiar with that module (it's out of the box!) here: https://docs.python.org/3/library/pathlib.html

  • `file_path` here is an explanatory variable to increase readability. Remember, code reads from top to bottom, not from left to right. – sur0k Sep 27 '21 at 23:01
