block Try and except

The input returns string. That being the case, before you account for the returns you should convert them.

In addition, you say that the example is two executions of the program, so it is understood that when receiving a non-numeric input the program, besides presenting the error message, is interrupted ( sys.exit ). / p>

As the same treatment is given for two inputs, it is better to create a function ( int_or_exit ) to avoid repetition of code.

import sys


def int_or_exit(int_string):
    try:
        int_valor = int(int_string)
    except ValueError:
        print("Erro, por favor, informe entrada numérica")
        sys.exit(1)
    return int_valor


input_numero_horas = input("Digite as Horas: ")
numero_horas = int_or_exit(input_numero_horas)

input_valor_hora = input("Digite a Taxa: ")
valor_hora = int_or_exit(input_valor_hora)

valor_total = numero_horas * valor_hora
print("Valor de Pagamento é:", valor_total)

The problem is that you are setting variables like INT after multiplication, this error means that you are multiplying strings , so the problem.

try this way:

numero_horas=input("Digite o numero de horas:")
valor_hora=input("Digite o valor hora:")
try:
    #print("Erro, digite numeros")
    valor_total=int(numero_horas)*int(valor_hora)
    print("Valor total", valor_total)
    valor=int(valor_total)
    print("Valor de Pagamento é:", valor)
except ValueError:
    print("Inicie programa novamente")
