How to get a GET parameter?

Question

Django

I make a request in which I pass a GET parameter. On the backend side, in the corresponding view, Jangi is trying to print this parameter to the console using the print statement. But in the console I get the following error message:

print('=-=-=', request.GET["user_id"])

At the same time, if I write the print statement like this: Then there is no error in the console, but it is displayed:
