Hello Campers!
After watching one of fCC’s python tutorials on youtube (This one) I did the follow along project for the terminal based blackjack game, and while the game was fun and the project good for showing off what the course taught, I felt like there could be some improvements made to the game itself that would make it far more enjoyable to actually play.
So after a few hours of tinkering that let my stretch my baby dev legs a bit more, I came up with this:

rank_value = {"A" : 11, "2" : 2, "3" : 3, "4" : 4, "5" : 5, "6" : 6, "7" : 7, "8" : 8, "9" : 9, "10" : 10, "J" : 10, "Q" : 10, "K" : 10}

if self.rank != "10":
front_face = [
f" _____ ",
f"|{self.rank} |",
f"| {self.suit} |",
f"| {self.rank}|",
f" ‾‾‾‾‾ "
]
else:
front_face = [
f" _____ ",
f"|{self.rank} |",
f"| {self.suit} |",
f"| {self.rank}|",
f" ‾‾‾‾‾ "
]
return front_face

I’m just patting myself on the back here for a pretty basic achievement but I am open to any feedback on the changes I made!
Thank you for taking the time to read my post and look over my code.
