The nuke.expression evaluates $gui once, then returns a 1 or 0 (true or
false). The you are setting the disable node to that "1" or "0".
Instead I guess you want to use the setExpression method on the disable
knob. This is like right-clicking disable, and clicking "add expression"
Also, you can find certain node classes with
nuke.allNodes("TheNodeClass"), which will work even if you change the
nodes name to something
So, something like:
for node in nuke.allNodes("Blur"):
node.setExpression("$gui")
