My solutions are aparently the same but the tester says that they are wrong, if someone can give me an answer.(I know my code is not elegant but anyway......):

def string_apl(string, k): string=string.upper() count = int(len(string)) sub_len= int(count/k) string2= [] string3= [] for i in range(k): string2.append(string[i * sub_len : (i + 1) * sub_len])

for palabra in string2:
    palabra_nueva=''
    for letra in palabra:
        if letra not in palabra_nueva:
            palabra_nueva += letra

    string3.append(palabra_nueva)

for item in string3:
    print(item)

string = input() k= int(input()) var= string_apl(string, k)
