Challenge 1: Get it right

Write a program that asks the user a question and keeps repeating the question until they get it right.

sky = input("What colour is the sky? ")
while sky != "blue":
print("That was wrong.")
sky = input("What colour is the sky? ")
print("Well done, you guessed it.")

Challenge 2: Average of any number of numbers

total = 0
count = 0
num = 0
while num != -1:
    num = int(input("Enter a number or enter -1 to average the numbers entered so far"))
    count = count + 1
    total = total + num
average = total / count
print(f"The average is {average}")

Challenge 3: Validating input

choice = 0
while choice < 1 or choice > 4:
choice = int(input("Enter a choice from 1 to 4: "))
print("You chose {choice}.")
