Hello,I am struggeling with the following (maybe it is quite simple):I am looking for a python script to zip two lists (#1: numbers and #2: point list) and then sort them by y-value and then by…Continue

Hello,I have a question about comparing unequal lists to eachother. I have a beam with 5 points, where on two points a reaction force occurs (see image):Points:                        Points with…Continue

### Zip list and sort by Y-value

Hello,I am struggeling with the following (maybe it is quite simple):I am looking for a python script to zip two lists (#1: numbers and #2: point list) and then sort them by y-value and then by x-value. For example:#1: Numbers                #2: Point list1: -39.3                        {0.35, 0.3, 0.0}2: -439.9                      {1.25, 0.3, 0.0}3: 513.2                       {1.65, 1.3, 0.0}4: -10.2                        {1.25, 1.3, 0.0}5: 326.1                        {0.35, 1.3, 0.0}Now…See More

"Something like this maybe (using in and list.index() to first check for value containment and then get index):"

"Yes something like that. But I want to script it with variabels so Grasshopper recognizes the reaction force per point itself and I dont have to select it by meself."

### Comparing unequal lists

Hello,I have a question about comparing unequal lists to eachother. I have a beam with 5 points, where on two points a reaction force occurs (see image):Points:                        Points with reaction force:      Reaction force:#0 {0.25, 0.1, 0.0}     {0.25, 0.1, 0.0}                    1071.43#1 {0.45, 0.1, 0.0}     {7.25, 0.1, 0.0}                    1928.57#2 {1.05, 0.1, 0.0}#3 {4.75, 0.1, 0.0}#4 {7.25, 0.1, 0.0}Now I want to create a new list with the reaction forces at each point and…See More

### Python script bug?

Hello,I encountered an very strange solution in a python script. I am trying to compare the X and Y-values of Endpoints. When I print the X values of the endpoints from different lines seperatly, they intersect. However when I compare the lines to eachother python states that it is false, which is very strange since they actually intersect (see images). Does somebody know if I am doing something wrong or if this is a bug in python?Thanks in advance,See More

"First of all thanks for your quick reply. And yes it works, the dispatch component and comparing the length of curves in combination with a cull pattern.  Thanks a lot Ibrahim "

"Hi Roman, Can't you do it with the dispatch component using a true/false pattern comparing length of curves in both lists ?"
