Description
Dynamo handles lacing on it’s own(provided that the python script is within a custom node), however sometimes you may have to handle multi-dimensional arrays by your self.
The solution is simple, you use recursivity. Basically you iterate through each element in the list and if the item is a list, then apply the iterate function to that item, if not then apply the custom function:
Solution
import re
### isIterable function determines if the object is an array or not
def isIterable(unit):
t1 = t2 = False;
if(isinstance(unit, (tuple, set, list, dict))):
t1 = True;
if(hasattr(unit, "__iter__")):
iterstr = str(unit.__iter__());
if(re.search("System.Array", iterstr)):
t2 = True;
return (t1 or t2);
### iterating over the list (if it's a list) or apply function
def iterateAndDo(elements, myFunction):
if(isIterable(elements)):
returnList = [];
for element in elements:
returnList.append(iterateAndDo(element, myFunction));
return returnList;
else:
return myFunction(elements);
### our custom function
def Log(input):
#do something here
return;
OUT = iterateAndDo(IN[0], Log)
