python os.listdir的替代方案os.scandir

import os
import shutil
data_path='D:/oanda/'   
target_path='D:/data/'
with os.scandir(data_path) as it:
    for entry in it:
        if not entry.name.startswith('.') and entry.is_file():
            file_name=entry.name
            pair='__'.join(file_name.split('__')[:2])
            shutil.move(data_path+file_name,target_path+pair+'/'+file_name) 
            print(file_name)
