three d arrays are like this. [[]]2 years ago

You can do this natively within Python. All a 3D array is is just an array of arrays of arrays, so you could make one as such: board = [[[]]] board0[0] = 52 # Would set the first element to 52 `2 years ago

In line 15, I don't know why you need to add the,0 at the end. I can't seem to figure it out. Credit goes to @Sabertooth, they wrote this wonderful co

@TheHappyCow Hi, It's because the other elements from line 41 are dependent on that. If you remove this ,0 from there, the indexes of the lists from line 41 goes out of range. This might be the answer to your question *Hope this helps Please mark my answer if this helps*3 years ago

Hi! The reason why you need an extra , 0 is because it is inside another array and the second index 0 is being used to calculate costs. is this what you want?3 years ago

Hi! Try changing the input variable to something else, maybe like text. This is because input is a reserved function.3 years ago

How do I change the main.py to something else?

Thanks for the help! I didn't expect so many people would answer so quickly. I appreciate it! Have a good day!3 years ago

You cant change main.py into anything else, but you can still import it, like this #In any other file import main Main.py is like a special file, it cant be renamed properly. its name when importing is main two underscores on each side3 years ago
Coder100
Sorry, that file is pinned and cannot be edited. You can use a hacky method to rename it, however. Hit ctrl+shift+s: rename main.py [new file].py However, then you will have to configure how the repl is run in order to make the repl work. Create a .replit file: run="python [new file].py" `3 years ago
