带有 python 和 wandbox API 的设备的 ioctl 不合适

Question

before you guys say this is a duplicate question.. its not. This is in python and im using the wandbox API. Heres my code

@bot.command()
async def linux(ctx):
  ez= os.popen("wandbox -f test.py 2> /dev/stdout").read()
  print(f"```{ez}```")

Im trying to make a linux command (discord.py) that everybody can use. Im trying to use the wandbox API though, its not working as expected. The code is supposed to run the file test.py.. Heres the code for test.py

import os
os.system("ls")

It should be returning with prog.py although im getting the error Inappropriate ioctl for device.
