kUn | Main Code for RoboCup SSL Reinforcement Learning Train | Machine Learning library

I worked on many fields in order to take my result that sorted by a to z. Here is the query that I wrote:

Given a small test data as follows:

It's my first project and I'm trying to pass multiple models to my ListView and get them to my template/index via different context_object_names but there seems to be shortcut or another way to do it that I'm missing.

This ANTLR4 parser grammar errors a 'no viable alternative' error when I try to parse an input. The only rules I know of that matches the part of the input with the error are the rules 'retblock_expr' and 'block_expr'. I have put 'retblock_expr' infront of 'block_expr' and put 'non_assign_expr' infront of 'retblock_expr' but it still throws the error.

input:

print(do { return a[3] })

full error:

line 1:11 no viable alternative at input '(do { return'

parser grammar:

When I run my grammar (lexer and parser) in powershell, it produces these errors:

I'm new to coding and could really use your help! I am trying to show a 'bestseller' image on a product based on a boolean. I am using Firestore for the database. I have managed to get the value of the 'bestseller' field on all the documents, but I don't know what to do next. This is my code so far. This shows the bestsellerImg on all of the products - instead of only the ones where the value = "True"

Here are two pictures to show what i mean :)

the swift file/class "ProductsVC" is controlling the ViewController with the collectionView in it.

Code from "ProductsVC"

Edit: I realize now that I should put down at least anything for general other than 'Lmao No'. I apologize for the inconvenience and headaches I've caused... maybe. Stack Overflow is a ruthless place.

So I was typing up a bot that used a Leveling system, and when I ran the code:

Main.py

Im trying to make a field longer if there's an error so I can fit the error message in it.

In addAccToDB.php I set $error to "Wachtwoorden komen niet overeen." if the 2 entered passwords do not match and I redirect the user back to createaccount.php. Back in createaccount.php $error appearently is still not set though so it doesn't add the class "extend" to the field to make it longer. This is what I tried:

createaccount.php:

so i made a list and i used tkinter for choosing a random data in list and showing that in a showinfo box. now i was just wondering if its possible to make a random image for random data. for eg i am making a app that generates a random anime name from the list but i want to add the anime picture also is there any way i can do that ? i haven't tried building it but here is what i have made so far.

i have no error i just want to have different picture for different names from the list chose randomly
