I am facing the problem of adding custom permission in Django. My idea is that when authorizing a user, if it belongs to group1, only the rows of group1 are displayed, and otherwise the rows of group2. There is a group field in the database table, it contains only two values group1 and group2. In the admin panel, I created 2 groups, respectively, and also included users in these groups. Also I created permissions and assigned them to each user.

My models.py

The following is a code to enter some details of students into a text file and from the main menu, the user can display them using option 2. My problem is in the section where it should display all the "Taken Courses by student". When I choose to display all data, the "mentioned section using the for loop only display the last value I enter when writing to the file. How can I make it display all my entries? The issue is under the showdata and displaydata functions.

I have android app created by Android studio with standard Navigation Drawer Activity pattern. On one of my fragments layout i have imageview, which allows users to load image from device when they tap it. There is a fragment code:

Given a string s, I want to find the substring of length k which contains the maximum number of vowels among the list ["a", "e", "i", "o", "u"] The user gets to input the string s and its length k. For exemple if s = "sfjfio" and k = 3 then the output should be the string "fio" If I have multiple substrings satisfying this condition then the output should be the substring which starts at the lowest index. If no substring satisfies the requirements then I want the output to be just the original string s back. I started with this code but I got kinda confused and stuck. It seems to work but doesn't always give the right answer when I try several examples. I just started with python a few days ago and not super knowledgeable yet. Any help would be really great !
