Hi,
I have been digging in the forum but can find anything around this…
I want to replace the non booleans in this list by a true value. What is the condition I’m looking for? how do I formulate it?
Thanks!
I’ve found a way around, using “replace items at index” as I have the list of the numbers in my mixed table. Still, if somebody could help me with the query above I’s be glad.
thanks!

Hi Maria,
I think your looking for this.
Yes! thanks Kulkul.
Hi guys,
I’ve been trying to convert the true values of a list by a numeric values from other list and remove the false values also. I’ve been using “Boolean Input to Variable String Output” from bakery nodes, “Combine by Pattern” from archi-lab nodes and also replacebycondition node. However I didn’t succed with any of them.
Just for making more clear my approach is from the first boolean list to get the following list:
[0] List
[0]2011200
[1]null
[2]null
[3]null
[4]null
[1] List
[0]null
[1]null
[2]null
[3]null
[4]null
[2] List
[0]null
[1]2971200
[2]null
[3]null
[4]null
[4] List
[0]null
[1]null
[2]1080000
[3]null
[4]3414576
[1] List
[0]null
[1]null
[2]null
[3]2971200
[4]null
Thanks for your time and help

Hi Alejandro,
here are two ways i found to solve your problem. I prefer design script option for obvious reasons I really don’t know why a can’t use list.map with replacebycondition…

Hi Mostafa,
Thanks a lot for your quickly answer and great solution. You are really good! 
Finally thanks to your help I managed to get the list of values that I was looking for.
Actually I didn’t know that you could use the programming language “Design Script” within the code block note. I thought that the only way of make your costume nodes in dynamo was by making your own python script. That’s why, I started to learn python some months ago.
What do you think that are the advantages of programming in “Design Script” vs “Python”?
Have a nice day,
Best regards,
Alejandro

You are most welcome.
I’m really not an expert in programing … I’m just on the process of learning python too, because I believe it is much more powerfull than design script as it allows you to interact directly with revit API.
Design script came more naturally after a year of using dynamo because it uses the same functions as nodes …
Hi Mostafa,
Thanks for your opinion regarding the advantages of using DS vs Python.
I’m agreed with you that python can be such a powerful tool in combination with dynamo.
Basically with a good knowledge of these, you can achieve with revit whatever you want. That’s why for me is really exciting to keep learning dynamo and python everyday
