Hi, I have a problem with a function in Python, which involves a tuple of tuples. When executing this assembly function calling the tuple of tuples votes:

votacoes = (
    (0, 15729, 220408, 1297, 0, 3040, 993, 0, 1354, 1046, 0, 3284, 99652, 19327, 0),

)

def assembleia(t):
    lst_votos = list (t)
    lst = []
    for e in t:
        lst = lst + [0]    

    n = (16, 3, 19, 3, 4, 9, 3, 9, 4, 10, 47, 2, 39, 9, 18, 6, 5, 9, 5, 6, 2, 2)
    lst_mand = list (n)
    lstm = []
    for i in n:
        lstm = lstm + [0]        

    for z in n:
        while z > 0:
            maior = lst_votos[0]
            for i in range(0, len(lst_votos)):
                if lst_votos[i] > maior:
                    maior = lst_votos[i]         

            for j in range(0, len(lst_votos)):
                if maior == lst_votos[j]:
                    p = j     

            lst[p] = lst[p] + 1

            lst_votos = lst_votos[:p] + [(lst_votos[p] * lst[p]) / (lst[p] +1)] + lst_votos[p+1:]

            z = (z - 1)

    return tuple(lst)

The error you give is:

line 61, in <module>
    lst_votos = lst_votos[:p] + [(lst_votos[p] * lst[p]) / (lst[p] +1)] + lst_votos[p+1:]
builtins.TypeError: unsupported operand type(s) for /: 'tuple' and 'int'

I can understand the reason for this error, but I can not get around and run it .... I can get it to work if I do one by one, now by calling the tuple, broke ... The idea is that afterwards a tuple is returned with the results of the voting distribution (later I will have to add that return, but I have not yet put it in the code).

One problem with your code is that you are manipulating tuples, when in fact you would like to manipulate integers that are part of these tuples.

The problem comes down to accessing data in arrays, that is, tuples and multidimensional lists.

For example, when you start your function, you are just transforming the outer tuple into a list, not the inner tuples:

def assembleia(t):
    lst_votos = list(t)

In this case, you would just be making this:

((10, 20, 30), (40, 50, 60))

If it became this:

[(10, 20, 30), (40, 50, 60)]

Suppose at last that:

lst_votos = [(10, 20, 30), (40, 50, 60)]

Later, when you do maior = lst_votos[0] , you are passing the first tuple as value to maior . What it will entail in:

>>> print(maior)
(10, 20, 30)

In this context, you want to assign the first value of this tuple to the variable maior , so you should pass the first element of the first tuple:

>>> lst_votos = [(10, 20, 30), (40, 50, 60)]
>>> maior = lst_votos[0][0]
>>> print(maior)
10

If you had three dimensions:

>>> exemplo = [((1, 2), 20, 30), (40, 50, 60)]
>>> print(exemplo[0][0][0])
1

To fix this, you will have to change several points of your code. I advise you to divide the problem into smaller parts, within functions:

A function that resolves the allocation of commands relative to a tuple, receiving as arguments the number of commands and a voting tuple, such as assembly ();
Another function that receives as arguments the command tuple and the tuple of tuples of votacoes, which leads to a loop calling the assembly () function n times.

So you will not have to access multidimensional data and make your code clearer.
