How to find files and save them to different folder in python

Question

I amt trying to find all relevant files and folders from local repository. e.g. I pulled projects from git to my local machine and I want to search for specific files(.txt) and save them to new folder in same pattern (root->dir-> file). Basically I want to get rid of any files which doesn't match name and extension but keep the same format. Thanks in advance.

You can traverse the directory tree finding the files you want with this:

import os, fnmatch

def find_files(directory, pattern):
    for root, dirs, files in os.walk(directory):
        for basename in files:
            if fnmatch.fnmatch(basename, pattern):
                filename = os.path.join(root, basename)

                yield filename

def find_files_to_list(directory, pattern):
    file_list = []
    for root, dirs, files in os.walk(directory):
        for basename in files:
            if fnmatch.fnmatch(basename, pattern):
                filename = os.path.join(root, basename)
                file_list.append(filename)

    return file_list

then copy the repository and do something like this:

wanted_files = find_files_to_list('/original_project/', '*.html')
for filename in find_files('/copy_project/', '*'):
    if filename not in wanted_files:
        os.remove(filename)
