Were I to do this, I'd make some changes (if you have it working, just consider this some code review, hand in what you have unless you are very keen). Create an enum for the 4 suits (clubs, hearts, ...). Create a class that contains both the suit and the value as properties. Figure out how to load the card image from the properties of the card class, and make the card image a read-only property that works once the image is loaded. Now you can build your deck with two nested loops (1..13) and (Heart .. Spade). Once the deck is built, tell each card to load its image. Then shuffle the deck — Flydog57 15 secs ago

Q: Generalized implementation of Binary Tree DFS and BFS traversals factored into one class using generators and lambdas. [python3]

josevilleThere are six Binary Tree DFS traversals (preorder, inorder, postorder, and their reverse counterparts). Their implementations can be very similar 1, so I factored out the core logic into a class Traverser (found in the first code block below). As an example, say you want the "inorder" traversal ...

Q: Does Angular (or other frontend framework with auto UI update) break Single Source Of Truth since using function within template should be avoid?

Ricky MoI know when building an Angular app (or other frontend framework with auto UI update by change detection), using function in a template is not recommended since it will result in the function being called every time when change detection runs.

Before you post at Code Review, make sure to read A guide to Code Review for Stack Overflow users, as some things are done differently over there - e.g. question titles should simply say what the code does, as the question is always, "How can I improve this?". Be sure that the code works correctly; include your unit tests if possible. You'll likely get some suggestions on making it more efficient, easier to read, and better tested. — Toby Speight 24 secs ago

@SᴀᴍOnᴇᴌᴀ - there appears to be no POST data sent with that POST request 🤦‍♂️
 
Asking for improvements to working code is a better fit for codereview.stackexchange.com. That being said, my immediate understanding of this problem is that there are 2 cases: 1) The numbers does only digits <=4, in that case replacing the left most digit with its +5 value is the correct solution. 2) The number does contain digits >= 5, in that case replacing the right most digit that is >= 5 with its +5 value will be the correct solution. eG if you take the number 145071 you replacing the 7 and getting 1450121 is the correct solution. — OH GOD SPIDERS 11 secs ago

1. You can't link code here, you have to include it in your post itself. 2. You appear to be asking mainly for a code review - StackOverflow is for getting help with issues, so you would be more likely to get this kind of help on codereview.stackexchange.com. 3. If you want to have both a code review and get a specific question answered, it's fine to make a post asking exclusively about the issue, and a separate post about the code review. — Random Davis 10 secs ago

Very unclear what you need help with. From the "listen to any feed back" statement it sounds like you are looking for general review of your code (which is not on-topic on SO - possibly suitable for Code Review. Can you please edit the question to clarify whether the code shown in the post works or it has some issues like does not compile/throws exceptions/does not return data you like?

This is a bit off topic for a few reasons, but I opted for "needs debugging details" as this question only seems to be asking for improvements to existing working code.

@Hanselmann - PEP 20 - The Zen of Python: There should be one-- and preferably only one --obvious way to do it. Column lookup by attribute doesn't cover all cases and its common to end up with a mix of column verses index lookup - ugly! Similar thing with map - its only useful in edge condtions.

Downvoted answer and left a comment.
 
@Mast Shouldn't we down vote the question as well?
 
@pacmaninbw What, for attempting to fix what was wrong with it in the first place?
 
OK I'll go undo my rollback, but leave my comment.
 
If the question was good, the answer is good and the question gets 'improved' after the answer has arrived, it's possibly answer invalidation.
If the answer arrived stating that the question was unclear and the question gets fixed up, the answer should've been a comment.
In my opinion. Feel free to state a different one.
