Help Printing Emojis

Code Help Python

Question:
I am making a CardGame hub where you can play all kinds of different card games, and I am starting with making War, and I want it to print some card emojis, but I can’t seem to get it to work.

Example hands.json

{"Player1": ["J", "7", "6", "10", "5", "2", "7", "J", "6", "K", "Q", "A", "2"], "Player2": ["3", "9", "J", "9", "K", "J", "7", "2", "Q", "Q", "9", "10", "K"]}

On windows, you can press Windows Key + . to bring up emojis. You can then select them and insert them directly into the code.

3

Getting the emojis isn’t my problem, I have some in the code already (I’m also not on Windows, but on iPad). I got the emojis from here → playing card decks ♣️.

4

What happens? What goes wrong?

5

@MilesWK it just doesn’t print out the emojis like it should, example → 

Player1 drew: A 
Player2 drew: 7
Winner: Player1
6

try using unicode and the chr() and ord() functions. Search them up on google to learn more

7

@AndrewDeng3 I looked up some Unicode things for the emojis, and they don’t exist for the cards. The emoji’s aren’t the problem, there isn’t any error. Just printing out the emojis is the problem, I think it has to do with the self.cards dictionary.

8

try using escape sequences:

# e.g. smiley
print("\U0001f600")

They work for me, check out my newest testing repl for a PoC

@python660 they still didn’t print out, maybe I setup the dictionary wrong →

Just a note, rather than using the @ symbol to mention people you can always reply using the reply button… but @ works too

I know, it’s just a habit though, because sometimes the Reply button doesn’t work. But the @ mention, in my experience always worked.

I believe that this isn’t an emoji printing problem, but a code problem. My head hurts too much from thinking, so I can’t really debug right now, but one comment I would like to make is that since you define the emojis as keys, they won’t be printed.

I fixed it, I did some messing around with setting amounts, and fixed some start_game() stuff as well →
