Delete multiple modifiers

thx barigazy,... but that is

thx barigazy,... but that is not what I need

I need a looping function

I tried but this is doesn't work for me

for obj in selection do
(
for m in obj.modifiers do
(
if classOf m==turboSmooth do deleteModifier obj m
if classOf m==skin do deleteModifier obj m
if classOf m==skin_wrap do deleteModifier obj m
)
)

I can make the buttons one by one like delete TurboSmooth , delete skin and delete skin wrap ...
but I need to delete all at once to the target modifier
