U-nderstand

Understand what the interviewer is asking for by using test cases and questions about the problem.

• Will the input always be an integer?
  • Yes.
• Should the function print anything out?
  • Yes, print the results from inside the function.

P-lan

Plan the solution with appropriate visualizations and pseudocode.

General Idea: Given a points total, print out the Blackjack game result.

1) Set up the function:
  a) Create a new function with a parameter representing the score
  b) Check each condition and print the appropriate result
2) Test the function for all possible results by:
  a) Calling the function

def blackjack(score):
	if score < 17:
	    print("Hit Me!")
	elif score < 21:
	    print("Nice hand!")
	elif score >= 21:
	    print("Bust!")
	else:
	    print("Blackjack!")
	    
	    
blackjack(21) # Output: "Blackjack!"
blackjack(19) # Output: "Nice hand!"
blackjack(10) # Output: "Hit me!"
blackjack(25) # Output: "Bust!"
