PyInstaller で生成された EXE でアプリケーション パスを見つけるにはどうすればよいですか?

import os
import sys

config_name = 'myapp.cfg'

# First, we check if the application is running as a script or as an EXE:
if getattr(sys, 'frozen', False):
    # If frozen as an EXE, we extract the path from sys.executable:
    application_path = os.path.dirname(sys.executable)
else:
    # If it's a script file (i.e., not frozen as an EXE), we use __file__:
    application_path = os.path.dirname(__file__)

# Finally, we join the path and the config file name to create the complete path:
config_path = os.path.join(application_path, config_name)
