Pycharm Error: Unresolved attribute reference 'isnumeric' for class 'int'

I was messing with a code that ask 2 numbers and let the user input what operation to do with them.

I need the input to be integers only, so i used .isnumeric, but i just can't make it go thru and it displays this error either i input numbers or letters.

if num1.isnumeric():

AttributeError: 'int' object has no attribute 'isnumeric'

Can some of you show me where is the problem?

here's the full code:

print('Você deverá digitar dois números e depois selecionar qual operação fazer com ambos.\\n')

    while True:
    num1 = int(input('Digite o primeiro número: '))
    
    if num1.isnumeric():
        break
    else:
        print("Apenas números, por gentileza")
    
    while True:
    num2 = int(input('Digite o segundo número: '))
    
    if num2.isnumeric():
        break
    else:
        print("Apenas números, por gentileza")
    
    operador = input()
    
    if operador == '+':
    print('O resultado é:', num1 + num2)
    elif operador == '-':
    print('O resultado é:', num1 - num2)
    elif operador == '*':
    print('O resultado é:', num1 * num2)
    elif operador == '/':
    print('O resultado é:', num1 / num2)
    
    else:
    print('operador invalido')

I don't know what to try.

isnumeric() is a function of str. You need to remove the int from surrounding the input and move it to after you have verified that isnumeric() is True.

You also have incorrect indenting. I don't know if that was just an issue when pasting the code into StackOverflow, but to sum it up, after a line that ends with a colon (:), the next line needs to have an increased indent, continuing until the end of the selection/iteration code block.
