+# Lab 4: Blackjack Advice
+
+# Let's write a python program to give basic blackjack playing advice during a game by asking the player for cards. 
+# First, ask the user for three playing cards (A, 2, 3, 4, 5, 6, 7, 8, 9, 10, J, Q, or K). 
+# Then, figure out the point value of each card individually. Number cards are worth their number, all face cards are worth 10. 
+# At this point, assume aces are worth 1. Use the following rules to determine the advice:
+
+#     Less than 17, advise to "Hit"
+#     Greater than or equal to 17, but less than 21, advise to "Stay"
+#     Exactly 21, advise "Blackjack!"
+#     Over 21, advise "Already Busted"
+
+# Print out the current total point value and the advice.
+
+# What's your first card? Q
+# What's your second card? 2
+# What's your third card? 3
+# 15 Hit
+
+# What's your first card? K
+# What's your second card? 5
+# What's your third card? 5
+# 20 Stay
+
+# What's your first card? Q
+# What's your second card? J
+# What's your third card? A
+# 21 Blackjack!

+# Version 2 (optional)
+
+# Aces can be worth 11 if they won't put the total point value of both cards over 21. Remember that you can have multiple aces in a hand. 
+# Try generating a list of all possible hand values by doubling the number of values in the output whenever you encounter an ace. 
+# For one half, add 1, for the other, add 11. This ensures if you have multiple aces that you account for the full range of possible values.
