How to rename path name?

I have .dcm files in a path like below (old_path);

old_path: Mass-Test_P_00016_LEFT_MLO_1/10-04-2016-DDSM-15563/1-cropped images-77287/000000.dcm

I have to rename the path like below (good_path);

good_path: Mass-Test_P_00016_LEFT_MLO_1/15563/77287/000000.dcm

Note that I keep only the last 5 digits in the sub-folders as shown above.

Please anyone show me how this must be done? This is my attempt...

os.chdir(path to data)
os.listdir()
>> ['Mass-Test_P_00016_LEFT_MLO_1', 'Mass-Test_P_00016_LEFT_MLO']

temp = os.walk('Mass-Test_P_00016_LEFT_MLO_1', topdown=False)
for root, dirs, files in temp:
    for name in files:
        old_path = os.path.join(root, name)
        print("old_path: ", old_path)
        first = old_path.split('/')[1][-5:]
        second = old_path.split('/')[2][-5:]
        #print(first, second)
        good_path = os.path.join(old_path.split('/')[0], first, second, old_path.split('/')[3])
        print("good_path: ", good_path)
        os.rename(old_path, good_path)

I was able to set the good_path as I want. But it is not overwriting the subfolders names.

You need to rename each node of your path from the root (the left most folder of old_path) to the leaf (your .dcm file). You might be interested in using os.renames instead of os.rename
