Hello,

I’m trying to make a simple for loop with the range equivalent of the number of rows in a dataset. I can’t seem to get the syntax correct. This is what I’ve tried so far:

```auto
DataSetTag = '[default]Folder/Tag1`

for x in range(len(system.tag.read(DataSetTag))):
	print x

for x in range(len(system.tag.read(DataSetTag).value)):
	print x

for x in range(data.getRowCount(DataSetTag)):
	print x

```

I assume this is really simple to solve, any help is appreciated.

Thank you

`print system.tag.read(DataSetTag).value.getRowCount()`
