is the * you are looking at means “Multiplication”?

Thanks for your attention.

Yes, I want to get the multiply this fraction(the data divide the number by the data from that group in order) by the data from the list.

Nice! Well done.

That is really helperful.

Could it be solved by Ironpython in the grasshopper,

The actual problem I meet is more complicated.

It is very doable. Unfortunately I’m not that great in python. But it can be as simple as getting the item’s branch and index .

AI comes to help:

```
import Rhino
# Sample data tree
data_tree = [[1, 2, 3], [4, 5], [6, 7, 8, 9]]
# Iterate through the data tree
for branch_num, branch in enumerate(data_tree):
for item_num, item in enumerate(branch):
# Extract the branch number and item number
print("Branch {0}, Item {1}: {2}".format(branch_num, item_num, item))
```
