Walking directories

I am searching for a specific directory (/android).

I know that in python I can walk directories with os.walk(root_dir) but the problem here is that I do not know if the directory that I am looking for is a child of root_dir or if its a parent directory of root_dir.

Is there any method that perform the same operation than os.walk() but in the opposite way?

Thanks.

I solved this issue with this code:

def copy_my_custom_class(current_dir):
    subdirs = os.listdir(current_dir)
    for subdir in subdirs:
        if (subdir == 'android'):   
            dest_file_path = os.path.join(current_dir, subdir, 'MyCustomClass.smali')
            shutil.copyfile('./files/MyCustomClass.smali', dest_file_path)  
            return 0

    copy_my_custom_class(os.path.dirname(current_dir))

Here is the solution that I chose however I have an error when parsing the absolute path to copy the file. I get this error, I think it is because I need absolute path, does someone know how to get an absolute path from a directory list?

FileNotFoundError: [Errno 2] No such file or directory: 'android\\MyCustomClass.smali'

here is my code:

def copy_my_custom_class(current_dir):
    subdirs = os.listdir(current_dir)       
    for subdir in subdirs:
        if (subdir == 'android'):       
            my_custom_class_path = os.path.join(subdir, 'MyCustomClass.smali')
            shutil.copyfile('./files/MyCustomClass.smali', my_custom_class_path)    

    copy_my_custom_class(os.chdir(current_dir))

You can go to parent directory of root_dir by using .. in os.path.abspath().

import os
parent_dir = os.path.abspath(os.path.join(root_dir, ".."))

Now you have parent_directory of root_dir in parent_dir, You can make it root_dir and use os.walk(root_dir) again.
