Hi all,
I’m having some issues with inserting an element into a list through python. I’m using the built-in function insert, but this is what I get.
Am I missing something here?
OUT = inicio[0]
OUT = inicio[0].insert(0,100)
OUT = list(inicio[0]).insert(0,100)
Thanks in advance!
import clr
clr.AddReference('ProtoGeometry')
import Autodesk.DesignScript.Geometry
from Autodesk.DesignScript.Geometry import *
clr.AddReference('DSCoreNodes')
from DSCore import *
lista = [0,1,2,3,4,5,6,7,8,9,10]
OUT = Insert(lista,5,100)
Don’t know what am I doing wrong?
Hi @T_Pover:
Thanks for your response. Following your guideline I’m trying to do this into a nested list, but I get an error:
this is the main list inicio:
this is ind_pisos:
error!:
for k in range(len(ind_pisos)):
for i in range(len(inicio)):
for j in range(len(inicio[i])):
if ind_pisos[k] > inicio[i][j] and ind_pisos[k] < fin[i][j]:
inicio[i].insert(j+1,ind_pisos[k])
else:
pass
OUT = inicio
What’s wrong?
What do you mean?
I copy pasted it from your previous post and all the indentations were spaces. Maybe there was a misaligned space, so I backspaced them all and then used tab to set the indentations.
I’m using PyCharm and checked what you said. still got the error. It seems like it reads inicio[i] not as a list, but as an object?
Here’s redoing your example:
import clr
clr.AddReference('ProtoGeometry')
from Autodesk.DesignScript.Geometry import *
#The inputs to this node will be stored as a list in the IN variables.
inicio = IN[0]
ind_pisos = IN[1]
fin = IN[2]
for k in range(len(ind_pisos)):
for i in range(len(inicio)):
for j in range(len(inicio[i])):
if ind_pisos[k] > inicio[i][j] and ind_pisos[k] < fin[i][j]:
inicio[i].insert(j+1,ind_pisos[k])
fin[i].inicio[i].insert(j,ind_pisos[k])
else:
pass
OUT = inicio@T_Pover. I mis-typed the previous code:
import clr
clr.AddReference('ProtoGeometry')
from Autodesk.DesignScript.Geometry import *
#The inputs to this node will be stored as a list in the IN variables.
inicio = IN[0]
ind_pisos = IN[1]
fin = IN[2]
for k in range(len(ind_pisos)):
for i in range(len(inicio)):
for j in range(len(inicio[i])):
if ind_pisos[k] > inicio[i][j] and ind_pisos[k] < fin[i][j]:
inicio[i].insert(j+1,ind_pisos[k])
fin[i].insert(j,ind_pisos[k])
else:
pass
OUT = inicio
In your example, it works fine, but in the code that I’m working with don’t.
So, my question is: I’m creating and rearranging lists through some for iterations and append functions, is there a change of the “type” o element doind that? I mean, is the “list” concept changing from a Dynamo list to a Python List?
It’s weird, I copy/pasted your code without changing anything and it works for me. I really don’t know what’s causing the problem here.
@T_Pover Thanks for your time!
Does anyone know what could be causing the error?
Now, I tried to change the algorithm, so:
for k in range(len(ind_pisos)):
for i in range(len(inicio)):
for j in range(len(inicio[i])):
if ind_pisos[k] > inicio[i][j] and ind_pisos[k] < fin[i][j]:
inicio[i].append(ind_pisos[k])
inicio[i].sort()
fin[i].append(ind_pisos[k])
fin[i].sort()
else:
pass
OUT = inicio
And I got the same error:
So, my guess is that this nested list is not being recognized as a list. What can be wrong here?
Could you try inicio[i].Add() instead of append?
It works with Add(), but when I set the sort() method, it shows the same error.
(the number added is at the end of the list)
It seems to be operating on a generic collection’s List instead of a python list… Which is werd because you haven’t imported the Generic Collections
Found it!
for k in range(len(ind_pisos)):
for i in range(len(inicio)):
for j in range(len(inicio[i])):
if ind_pisos[k] > inicio[i][j] and ind_pisos[k] < fin[i][j]:
aux = list(inicio[i])
aux.insert(j + 1, ind_pisos[k])
aux2 = list(fin[i])
aux2.insert(j, ind_pisos[k])
inicio[i] = aux
fin[i] = aux2
else:
pass
OUT = inicio
I turned it into a list befor getting into a insert().
Thanks for your time!
