Beginners Coding Error, While Loop Triggering 2 Messages

Question

I am a beginner that just started learning python this Monday and one of the first hurdles I am getting into is while loops. I was trying to code a number guessing game and when I enter the correct answer it will give me "Wrong Guess" and "Correct Guess" as outputs. I have been staring at this problem wondering why this is happening but I can't figure it out. Can someone explain why this is happening? Thanks in advance!

secret_number = 9
guess = ''
i = 0
while guess != 9 and i < 3:
    guess = int(input("Guess Number: "))
    i += 1
    print('Wrong Guess!')
if guess == 9:
    print('Your Correct!')
if i == 3:
    print('You lost!')

Answer 1

You need to trace your code line by line. Even if your answer was correct, the print('Wrong Guess!') would still execute.

Instead, I would check if the answer is correct inside the loop.

Note: there's a bug in your code - you should be using secret_number variable instead of explicitly writing 9.

You should also only add i for wrong guesses to prevent saying you lost although you did it in 3 tries.

while guess != secret_number and i < 3:
    guess = int(input("Guess Number: "))
    if guess == secret_number :
        print('Your Correct!')
    else:    
        print('Wrong Guess!')
        i += 1

Answer 2

You were getting both the messages together when you entered 9 as the input because the input statement and the Wrong Guess statement are both in the same while loop. Meaning once the code asks you to guess a number, it would then increment i and then print Wrong Guess. Only after doing all three it would go back and check for the conditions of the while loop. Because the conditions fail, for guess = 9 the next lines of code are implemented. which give you the Correct Guess output.

To get the desired output do this,

secret_number = 9
guess = ''
i = 0

while True:
  if i < 3:
    guess = int(input("Guess Number: "))
    if guess == secret_number:
      print("Correct Guess")
      break
    else:
      print("Wrong Guess")

    i += 1

  else:
    print("You've run out of lives.")
    break

Answer 3

This is another way to get what you're looking for:

secret_number = 9
guess = ''
i = 0
while guess!= secret_number and i<3:
    guess = int(input("Guess Number:"))
    if guess == secret_number:
        print("Your Correct!")
        break
    print("Wrong Guess!")
    i+=1

if i == 3:
    print('You Lost!')
