Description
The tcl_interp function is used to pass a string to the TCL interpreter.
Suggested Solution
Follow this example:
filename = "10002451_000_001.ply"
_tcl_interp("set mySimplifier [create HxSimplifier]")
_tcl_interp("$mySimplifier attach " + str(filename))
This approach works as a standard string concatenation in Python.
