Python - 猜数字游戏：没有 output

Question

What am I doing wrong here? I am trying to build a guessing a number game but not sure why the console doesn't display anything?!

import random

    game_random_number = random.randint(1, 100)
    game_active = True  
    
    
    while game_active:  
      game_start_message = "guess a number between 1 and 100"
      user_guess = int(input()) 
    if user_guess == game_random_number:
      print("You guessed it correctly")
      game_active = False
    elif user_guess < game_random_number:
      print("Too low guess again")
    else:
      print("Too high, guess again")

Answer 1

It works fine with the correct indentation. You otherwise fall in an infinite loop where you do nothing but request user to input a number.

import random

game_random_number = 42 # just for the test
game_active = True  
    
    
while game_active:  
    game_start_message = "guess a number between 1 and 100"
    user_guess = int(input()) 
    if user_guess == game_random_number:
        print("You guessed it correctly")
        game_active = False
    elif user_guess < game_random_number:
        print("Too low guess again")
    else:
        print("Too high, guess again")

example:

1
Too low guess again
2
Too low guess again
50
Too high, guess again
42
You guessed it correctly

NB. game_start_message = "guess a number between 1 and 100" doesn't do anything. Maybe you should rather print this string before the loop?

Answer 2

You did your indentation wrong, causing your if...elif...else structure to fall outside of the while loop, since that while loop never stops, it will keep asking for user inputs and never actually print anything else

Here is your code with the correct indentation:

import random

game_random_number = random.randint(1, 100)
game_active = True  

while game_active:  
    game_start_message = "guess a number between 1 and 100"
    user_guess = int(input())

    if user_guess == game_random_number:
        print("You guessed it correctly")
        game_active = False
    elif user_guess < game_random_number:
        print("Too low guess again")
    else:
        print("Too high, guess again")
