Question
(Game: lottery) Revise Listing 4.10, Lottery.py, to generate a three-digit lottery number. The program prompts the user to enter a three-digit number and determines whether the user wins according to the following rules:
1. If the user input matches the lottery number in the exact order, the award is $10,000.
2. If all the digits in the user input match all the digits in the lottery number, the award is $3,000.
3. If one digit in the user input matches a digit in the lottery number, the award is $1,000.
Answer
SOURCE CODE
import random
# Generate a lottery number
lottery = random.randint(100, 999)
# Prompt the user to enter a guess
guess = eval(input("Enter your lottery pick(three digit): "))
# Get digits from lottery
lotteryDigit3 = lottery % 10
lottery //= 10
lotteryDigit2 = lottery % 10
lottery //= 10
lotteryDigit1 = lottery % 10
# Get digits from guess
guessDigit3 = guess % 10
guess //= 10
guessDigit2 = guess % 10
guess //= 10
guessDigit1 = guess % 10
print("The lottery number is", lottery)
# Check the guess
if guess == lottery:
print("Exact match: you win $10,000")
elif (guessDigit3 == lotteryDigit3 and guessDigit2 == lotteryDigit1 and guessDigit1 == lotteryDigit2):
print("Match all digits: you win $3,000")
elif (guessDigit1 == lotteryDigit1
or guessDigit1 == lotteryDigit2
or guessDigit1 == lotteryDigit3
or guessDigit2 == lotteryDigit1
or guessDigit2 == lotteryDigit2
or guessDigit2 == lotteryDigit3
or guessDigit3 == lotteryDigit1
or guessDigit3 == lotteryDigit2
or guessDigit3 == lotteryDigit3):
print("Match one digit: you win $1,000")
else:
print("Sorry,no match")
OUTPUT
Enter your lottery pick(three digit) : 324
The lottery number is 2
Match one digit: you win $1,000
