python - subprocess ls Examples/* 没有这样的文件或目录

Question

>>> import subprocess
>>> child = subprocess.Popen(["ls", "examples/*"], stdout=subprocess.PIPE)
>>> ls: examples/*: No such file or directory

但是从终端它可以工作

Beagle:kumarshubham$ ls examples/*
examples/convert_greyscale.py       examples/feat_det_harris_corner.py  examples/read_display_image.py
examples/example_set_roi.py     examples/manipulate_img_matplotlib.py   examples/remove_matplotlib_cache.py

有人可以指导我哪里出错了吗？

Answer 1

import subprocess
child = subprocess.Popen(["cd /to-your-PATH/; ls", "examples/*"],shell=True, stdout=subprocess.PIPE)
child.stdout.read()
