how do i write this code (easy way), python problem?

  • I am very new in Python, and I am really surprised at the following line of code.

    p, q = [int(x) for x in input().split()]

    how to write basic??

  • You can make a loop instead to understand better, but the code won't work because the logic is false:

    your_input = input().split() 
    list_ = []
    for x in your_input:
    p, q = list_

    The .split() put the str in input in a list so you just have one element and one loop. But the p,q = at the end suggests it waits two elements in the list. So it can't work. Maybe you can delete the .split() if you want each digit of a number less than 100. Depends on the result you want.

    You can use Mongoose 'remove' middleware.

    For example:

    authorSchema.pre('remove', (next) => { storySchema.remove({authorSchema_id: this._id}).exec(); next(); });

    And documentation.

    Since it involves directly interacting with Mongoose and MongoDB, I'd suggest doing it in Mongoose middleware. Here's how you'd remove all the stories from a certain Author object:

    let myAuthor = new Author(/* all the props */); myAuthor.stories = [];

    my friends, I have about 200 ajax handlers, I designed one part of the app that keeps the application in maintenance. My question is, how can I disable all AJAX handlers for normal users (non-admin users)? Normally, I need to check the user capability in every method, which is timed operations.
