Inside method but loop still getting expected unqualified-id error C++

I have a quick question. I have read about "expected unqualified-id" errors and how they occur when a loop is outside of a method. The issue I am having is that the loop is inside a method and I am still getting this? Any assistance would be greatly appreciated.

The error in compiler:

   expected unqualified-id
for(auto template : filtered) {
         ^

The code:

py::str process(string text){
    //some code...
    for(auto template : filtered) {
        //some more....
    }
    //a return
}
