I need to calculate the sum of several elements in different lists (from index 0).
lista1 = [154,12,998,147]
lista2 = [897,123,998,59877]
lista3 = [3,789,111,555,699]
This would be the simplistic way:
soma = lista1[0]+lista2[0]+lista3[0]
But I need to extract the values and apply the methods rolling().sum()
lista4 = pd.Series([154,897,3])
lista4.rolling(2).sum()
something like that !!
If you have a list of lists:
lista1 = [154,12,998,147]
lista2 = [897,123,998,59877]
lista3 = [3,789,111,555,699]
listas = [lista1, lista2, lista3]
You can create a list of the first elements by doing:
primeiros = [lista[0] for lista in listas]
Thus,% w / w of% will be the list [154, 897, 3].
As suggested in the comments, one possibility is to define a function that returns the values of a certain list index:
def get_on_index(*listas, index=0):
return [lista[index] for lista in listas]
So, if you need all the values that are in index 2, just do:
valores = get_on_index(lista1, lista2, lista3, index=2) # [998, 998, 555]
