Correlating vectors through the Python indexes

Question

I have the following vectors:

posicao_1 = [4, 62, 24, 18, 47, 62, 63, 78, 68, 87, 24, 18, 6, 8, 12, 17]

posicao_2 = [43, 61, 21, 19, 46, 63, 68, 72, 66, 89, 29, 10, 8, 7, 6, 15]

I need to search the vector POSICAO_1 the value [24, 18].

posicao_1 = [4, 62, **24, 18**, 47, 62, 63, 78, 68, 87, **24, 18**, 6, 8, 12, 17]

We can observe that they are found in the indexes [2, 3] and [10, 11] of the vector POSITIO_1.

After locating these values, I need to go through the POSIO_2 vector and assign random and EQUAL values in the INDEXES [2, 3] and [10, 11] that I located in the POSIO_1 vector. For example:

Would have to assign random and EQUAL values:

posicao_2 = [43, 61, **21, 21**, 46, 63, 68, 72, 66, 89, **21, 21**, 8, 7, 6, 15]

Would someone please help me?

I’m sorry, in case I wasn’t clear, I tried to explain as much as possible!

Answer 1

Starting from the code of your last question you just need to create a list of indices and save the elements where that code is placing the random ones. Then use it to replace in the second vector posicao_2

Thus:

import random
aleatorio = random.randrange(0,200)

posicao_1 = [4, 62, 24, 18, 47, 62, 63, 78, 68, 87, 24, 18, 6, 8, 12, 17]
posicao_2 = [43, 61, 21, 19, 46, 63, 68, 72, 66, 89, 29, 10, 8, 7, 6, 15]
indices = [] #lista criada aqui

for j in range(len(posicao_1)):
    if posicao_1[j] in [24,18]:
        posicao_1[j] = aleatorio
        indices.append(j) #indice adicionado aqui, quando coloca aleatorios em posicao_1

for i in indices: #atribuição em posicao_2 com base nos indices
    posicao_2[i] = aleatorio

Edit

So that the exchange is done only by researching [24,18] as a sub-array is already necessary to modify a little the logic that was being made.

...
#imports e posições para cima iguais 
pesq = [24,18]

#construir os indices verificando se a partir de cada posição o subarray existe no principal
indices = [x for x in range(len(posicao_1)) if posicao_1[x:x+len(pesq )] == pesq ]

#para cada indice substituir o subarray pela mesma quantidade de aleatorios
for i in indices:
    posicao_2[i: i+len(pesq)] = [aleatorio] * len(pesq)

To search multiple tuples just transform the search array into an array of tuples and create another one for:

pesq = [[24,18], [62,63]]

for p in pesq:
    indices = [x for x in range(len(posicao_1)) if posicao_1[x:x+len(p)] == p ]

    for i in indices:
        posicao_2[i: i+len(p)] = [aleatorio] * len(p)
