Hello everyone, here again..

numero = int(input('informe o pedido\n:'))
pedido = open(f'Pedidos_test\{numero}.txt', 'r')
teste = []
testa = []
cont = 0
indic_pedido = 0
for linha in pedido:
    linha = linha.rstrip()
    novo = int(linha)
    print(novo)

its giving me the error:
Traceback (most recent call last):
File "C:/Users/ivinj/PycharmProjects/mundo3/estresseeeeee.py", line 9, in <module>
novo = int(linha)
ValueError: invalid literal for int() with base 10: ''
