將HFSS個別輸出的遠場圖更名為port的名稱

import os

path = 'd:/demo_FFD'

with open(os.path.join(path, 'exportelement.txt')) as f:
    text = f.readlines()

for line in text[1:]:
    try:
        port_name, file_name = line.strip().split()
        port_name = port_name.split(':')[0]
        os.rename('{}/{}.ffd'.format(path, file_name), 
                  '{}/{}.ffd'.format(path, port_name))
    except:
        pass
