Question: I am trying to iterate through a loop (selecting verts) in maya python, but am botching the syntax of concatenating the variable (sel) correctly in the loop...

```
sel = mc.ls(sl=True)
for num in range(0,noOfVerts, 2):
    mc.select("sel.vtx[%d]" % num, add = True)

```

Is using the variable as a string instead of the object itself

You can use <http://exacttarget.github.io/fuelux/> or on <http://bootstrapvalidator.com/examples/> check our Toggling example
You could give "exclude" option a try.
