I'm not sure how to fix this while loop to give "invalid entry" for when the input is not 8 or 9 but proceeed normally or break when the valid answer is given

x = ""

while True:             # Loop continuously
    game_type = int(input("Enter game type, either 8-ball or 9-ball with a single number (aka = 8 or 9): "))   # Get the input
    if game_type != "8" and game_type != "9":
      print(x)
      print("Invalid game type, please enter 8 or 9")
      print(x)
    elif game_type == 8 or game_type == 9:       # If it is a blank line...
      break 

print("the game type is",game_type)

What I have tried:

I've tried a variety of while formats but cannot seem to translate it successully into this program

You are converting the input to an integer but then you compare it to a string.

Python

while True:             # Loop continuously
    game_type = int(input("Enter game type, either 8-ball or 9-ball with a single number (aka = 8 or 9): "))   # Get the input
    if game_type != 8 and game_type != 9:
      print(x)
      print("Invalid game type:", game_type, "please enter 8 or 9")
      print(x)
    else:
      break 

print("the game type is",game_type)

You need to make your mind and choose, input is string or number, not both.

Python

x = ""

while True:             # Loop continuously
    game_type = int(input("Enter game type, either 8-ball or 9-ball with a single number (aka = 8 or 9): "))   # Get the input
    if game_type != "8" and game_type != "9":
      print(x)
      print("Invalid game type, please enter 8 or 9")
      print(x)
    elif game_type == 8 or game_type == 9:       # If it is a blank line...
      break 

print("the game type is",game_type)

While loop giving invalid input even when valid # is input
