how to make sure an input is from the wanted type

[menator01]

You could use a try block.

import random

RNumber = random.randint(1, 10)

while True:
    try:
        user_input = int(input('Guess a number\n>> '))
    except ValueError:
        print('Please use only whole numbers')
        continue
    else:
        if user_input > RNumber:
            print('Number is to high')
        elif user_input < RNumber:
            print('Number is too low')
        else:
            print(f'Congradulation! You guessed the number {RNumber}')
            RNumber = random.randint(1,10)
