linux 不用cd和ls,如何使用CD和LS之类的Linux终端命令？

如何向Python脚本添加终端命令？

我有一个大文件夹的图片/视频/文件夹更多的图像/视频，我想把它们组织在一个HTML文件(首页.html). 在

脚本首先列出目录中的所有文件：def listFiles():

command = "ls"

output = Popen(command, stdout=PIPE) #This is the only way i found to run LS in terminal and get the output

x = str(output.stdout.read())

x = x[2:-3]

x += (" ")

x = re.sub(r"\\n", " ", x)

y = ""

finalLIST = list()

for o in x:

if o == " ":

finalLIST.append(str(y))

y = ""

else:

y += o

return finalLIST #returns a list with all files in the current directory

然后检查文件是图像还是视频，如果是视频，则添加到HTML文件中：

^{pr2}$

如果它是一个图像，它会添加：

代码是：def organize():

DIRECTORIES = listFiles()

IMAGE = [".png", ".jpg"]

VIDEO = [".webm", ".mp4"]

for x in DIRECTORIES:

if not re.search(".", x):

#This means that it is a directory

#I want to CD into this directory and run listFiles() and then organize() it. How i do it?

else:

for y in IMAGE:

ADDimg = "\n\n"

if re.search(y, x):

with open(FirstPage.html) as f:

for line in f:

if line = "":

f.write(ADDimg)

break

f.write(ADDimg)

for y in VIDEO:

ADDvideo = """\n

"""\" type="video/WebM/mp4">

Video not suported!

\n

"""

if re.search(y, x):

with open(FirstPage.html) as f:

for line in f:

if line = "":

f.write(ADDvideo)

break

这是第一页.html以下内容：

The first page

我希望这个脚本列出目录中的文件，将其中的所有图像/视频添加到HTML文件中，然后cd到那里的文件夹中，并递归地执行相同的操作。有什么建议吗？在

谢谢！在
