tak na szybko zrobione:
bledne_pesele = []
with open('dane.txt', 'r') as file:
for item in file:
pesel = list(item.replace("\n",""))
for i in range(len(pesel)):
pesel[i] = int(pesel[i])
pesel_check = (1*pesel[0]+3*pesel[1]+7*pesel[2]+9*pesel[3]+1*pesel[4]+3*pesel[5]+7*pesel[6]+9*pesel[7]+1*pesel[8]+3*pesel[9]+pesel[10])%10
if pesel_check != 0:
bledne_pesele.append(pesel)
print(bledne_pesele)
