Hello all.
I am attempting to create a script to automate placing numerous cones into a paraview scene for me. I have run into issues with the following code block:
```
tree = Cone()
tree.Center = treeCenter.split(',')
tree.Radius = treeRadius
tree.Height = treeHeight
tree.Direction = 0,0,1
```
I get type errors from this code, which do not still occur if I instead manually type the data into the paraview GUI python shell.

Do you have an example of the error that occurs?

Yes. The whole error reads like this:
```
Traceback (most recent call last):

I think there’s just one line missing yet 🙂 . What’s the full `TypeError` block?

Oh, I suspect it is your `treeCenter.split(',')` line. That is a list of strings rather than a list/tuple of integers as I expect `Center` probably wants. Does `map(int, treeCenter.split(','))` work?

Tested that out, got a different error, but on the line prior. I should’ve mentioned that line 36 is the `treeCenter.split(',')` line.

Right, Python3 made those iterables. Wrap the `map()` call with `tuple()`.

Oh I see! Forgive me, I’m not the most familiar with python.

That appears to have worked! Cheers, Ben!!!
