how to loop through certain directories in a directory structure in python?

Question

I have the following directory structure

As you can see in the pics, there are a lot of .0 files in different directories. This directory structure exists for 36 folders(Human_C1 to C36) and each Human_C[num] folder has a 1_image_contours folder which has a contours folder with all related .0 files.

These .0 files contain some co-ordinates(x,y). I wish to loop through all these files, take the data in them and put it in an excel sheet(I am using pandas for this).

The problem is, how I loop through only these set of files and none else? (there can be .0 files in contour_image folders also)

Thanks in advance

Since your structure is not recursive I would recommend this:

import glob
zero_files_list = glob.glob("spinux/generated/Human_C*/*/contours/*.0")
for f in zero_files_list:
    print("do something with "+f)

Run it from the parent directory of spinux or you'll have no match!

It will expand the pattern for the fixed directory tree above, just as if you used ls or echo in a linux shell.
