Python, how to set index properly

Question

I have a question for you.

I have the following code:

defaults = list(0 for m in range(12))
index=6
totale=5
for i in index:
    defaults[i]=totale

But give me error TypeError: 'int' object is not iterable . I want to set the value totale for each month starting from the index untill the end of the year, but the [index:] does not works. In other words I want to obtain the following result:

[0,0,0,0,0,5,5,5,5,5,5,5]

Answer 1

I'm not clear what the variable types are, but you can use a simple for loop

index=month
for i in index:
    fondo_immobbilizzazioni_mat[tipologia][i] = totale

Note, it'll only work if month is of type list/array.

Answer 2

Try with:

for i in range(index, 12):
    defaults[i]=totale

Answer 3

Given the values of index and totale , all you need to do is the following:

defaults = [0] * index + [totale] * (12 - index)

Another option, slightly more complex to read, but (possibly) marginally more memory-effective, since it would not create any temporary lists, would be:

defaults = [0 if i < index else totale for i in range(12)]

It really does not matter much which you use, as long as this line is not called an excessive number of times.
