#2. In the game Yahtzee, players roll five dice. A Yahtzee is when all five dice are the same. Write a program that simulates rolling five 10,000 times and counts how many Yahtzees occur. Print out what percentage of the rolls come out to be Yahtzees.
from random import randint
yahtzee = 0
for a in range(10000):
    x = random.randint(1,6)

percentage = (yahtzee/10000)*100
print("percentage of rolls come out is: ", percentage)

# 4. Write a program that asks the user to enter a string. If the string is at least five characters long, then create a new string that consists of the first five characters of the string along with three asterisks at the end. Otherwise add enough exclamation points (!) to the end of the string in order to get the length up to five.
