# Lab 4: Blackjack Advice
2+
3+
# Let's write a python program to give basic blackjack playing advice during a game by asking the player for cards.
4+
# First, ask the user for three playing cards (A, 2, 3, 4, 5, 6, 7, 8, 9, 10, J, Q, or K).
5+
# Then, figure out the point value of each card individually. Number cards are worth their number, all face cards are worth 10.
6+
# At this point, assume aces are worth 1. Use the following rules to determine the advice:
7+
8+
# Less than 17, advise to "Hit"
9+
# Greater than or equal to 17, but less than 21, advise to "Stay"
10+
# Exactly 21, advise "Blackjack!"
11+
# Over 21, advise "Already Busted"
12+
13+
# Print out the current total point value and the advice.
14+
15+
# What's your first card? Q
16+
# What's your second card? 2
17+
# What's your third card? 3
18+
# 15 Hit
19+
20+
# What's your first card? K
21+
# What's your second card? 5
22+
# What's your third card? 5
23+
# 20 Stay
24+
25+
# What's your first card? Q
26+
# What's your second card? J
27+
# What's your third card? A
28+
# 21 Blackjack!

# Lab 7: Credit Card Validation
2+
3+
# Let's write a function credit_card_validator which returns whether a string containing a credit card number is valid as a boolean. The steps are as follows:
4+
5+
# Convert the input string into a list of ints
6+
# Slice off the last digit. That is the check digit.
7+
# Reverse the digits.
8+
# Double every other element in the reversed list (starting with the first number in the list).
9+
# Subtract nine from numbers over nine.
10+
# Sum all values.
11+
# Take the second digit of that sum.
12+
# If that matches the check digit, the whole card number is valid.
13+
14+
# Here is a valid credit card number to test with: 4556737586899855

19+
