我无法检查目录中可用的文件

Question

我正在尝试读取当前目录中的 csv 文件。为此，我想检查当前目录中存在的所有文件。我试过用 check_output 函数来做。但是，我收到了这个错误，我无法弄清楚如何处理它。这是我尝试过的代码：

from subprocess import check_output
print(check_output(["ls","../input"]).decode('utf8'))

这是我收到的错误：

FileNotFoundError                         Traceback (most recent call last)

您可以通过以下方式获取当前目录中所有文件的列表：

import os
files = os.listdir('./')
