Screwing Up looping in Generator

[Sayth Renshaw]

Untested as i wrote this in notepad at work but, if i first use the generator to create a set of filenames and then iterate it then call the generator anew to process file may work?

Good idea or better available?

def get_list_of_names(generator_arg):
    name_set = set()
    for name in generator_arg:
        base = os.path.basename(name.name)
        filename = os.path.splitext(base)[0]
        name_set.add(filename)
    return name_set



 for file_name in name_set: 
     directory = "output"
         with open(os.path.join(directory, filename, 'w', newline='') as csvf: 
            for file in rootobs: 
              # create and write csv
