Question

When coding in Python, I often need to write a function like this one:

def delete_dir(dir_name):

    if os.path.exists(dir_name):
        reply = raw_input("Delete directory "+dir_name+"? [y/[n]] ")
        if reply== y :
            os.system( rm -r  +dir_name)
        else:
            print "Aborting..."
            sys.exit()

Which is basically just a remove command with a user prompt to double-check (I also have one for deleting files). Given the large amounts of Python modules out there, including in the standard library, I m wondering if something like this already exists out there?

Answer 1

It wouldn t be a Python thing, but if you keep using os.system() to make the delete call, you can pass the -i parameter to rm. The man page explains it:

-i prompt before every removal

EDIT: I just read your code again and it looks like you re only prompting once before the entire delete process, not for each file. You might be interested in the -I flag instead:

-I prompt once before removing more than three files, or when removing recursively. Less intrusive than -i, while still giving protection against most mistakes

Answer 2

to remove directory, use os module os.rmdir(), os.removedirs(). Or shutil.rmtree() .check the docs for more information

Answer 3

well ,you could save this function in a module and reuse it in other modules,that way ,your problem will be solved !
