Система не может найти указанный файл для check_output

Question

я бегу следующие в окнах:

from subprocess import check_output 
check_output(["dir", "D:/C_Drive/Desktop/Kaggle"]) 

я получил следующую проблему, «D:/C_Drive/Desktop/Kaggle» в настоящее время является папка на моем рабочем столе.

добавить shell=True будет оштрафован

from subprocess 

import check_output print(check_output(["dir", "D:\\C_Drive\\Desktop\\Kaggle"],shell=True).decode("utf-8")) 

вдохновлен этой должности Windows can't find the file on subprocess.call()
