python - delete all files and subfolders (including code) under the folder

Use python to delete all files and subfolders under a folder, you need to use recursion.

Because direct os.remove cannot delete folders, os.rmdir cannot delete folders containing files.

Go directly to the code:

def deldir(dir):
    if not os.path.exists(dir):
        return False
    if os.path.isfile(dir):
        os.remove(dir)
        return
    for i in os.listdir(dir):
        t = os.path.join(dir, i)
        if os.path.isdir(t):
            deldir(t)#重新调用次方法
        else:
            os.unlink(t)
    os.rmdir(dir) #递归删除目录下面的空文件夹
