python how to delete all files whose name is a date in a folder

Question

I have a folder with two categories of folder naming

1st category folders are the ones that naming is a date
2nd category folder are the one that has a fixed name ‘master’.

Please refer to below screenshot.

How can I remove the all the ‘date’ folders and keep the ‘master’ folder by python?

Before I use below code to delete all the folders, but now I want to keep master folder.

try:
    shutil.rmtree('../../test/subtest/')
except OSError as e:
    print ("Error: %s - %s." % (e.filename, e.strerror))

This link contains the documentation of the module shutil. The first sentence of this documentation says:

The shutil module offers a number of high-level operations on files and collections of files. In particular, functions are provided which support file copying and removal. For operations on individual files, see also the os module.

As suggest by the previous sentence a solution for the problem is by the use of os module.

Use `os` module to list folders

Try this code:

import os
import shutil

parent_dir = '../../test/subtest/'
my_list = os.listdir(parent_dir)
for sub_dir in my_list:
    if sub_dir != 'master':
        print("deleting folder: " + sub_dir)
        try:
          shutil.rmtree(parent_dir + sub_dir)
        except OSError as e:
          print ("Error: %s - %s." % (e.filename, e.strerror))

I add the import of the module os which permits to obtain the list of sub directory inside the parent dir; see the instruction:

`os.listdir(parent_dir)`

The deleting does not check if the sub-folder name contains a date but only if its name is different from 'master', but, if I have understood your question, I think that this is what you need.
