How to check if there is a repeated string in a list?

Question

I would like to learn an easier way to check all items on a list and search for repeated strings.

I’m currently doing it this way:

elif "azul" in fios[0] and fios[1] or "azul" in fios[1] and fios[2] or "azul" in fios[0] and fios[2]:
    print("Corte o último fio azul")

My intention is to check if there is more than one "blue" inside the yarn list, the code is working, but I’d like to make it more practical.

Just use the method count of the object list:

cores = ['azul', 'amarelo', 'vermelho', 'preto']

print(cores.count('azul'))  # 1

cores = ['azul', 'amarelo', 'vermelho', 'azul']

print(cores.count('azul'))  # 2
