9 <:del:>

<:del name:>

This tag deletes the local variable named by name from your STML document. It's identical to the Python statement del name. You will use this tag very rarely, but it's there if you need it.

In this example, the variable named myVar is set to the integer 5, then deleted from the variable namespace. The third tag, which tries to access the variable name, results in a NameError, meaning that nothing exists under that name:

<:set myVar `5`:>
<:del myVar:>
<:val `myVar`:>
