Python find similiar files in given folder -

i'm trying write function find similiar files name (song.mp3, song1.mp3, (1)song.mp3) in specified folder. have now:

def print_duplicates(source):     files_list = []     new_list = []      dirpath, dirnames, filenames in os.walk(source):         fname in filenames:             if ('\w*' + fname + '\w*') in files_list:                 new_list.append(os.path.join(dirpath, fname))             else:                 files_list.append(fname)      in new_list:         print(a) 

if filename wasn't before in files_list added, if added new_list path. way have list of 'duplicate' files. it's not working, new_list remains empty. correct mistakes? part of code wrong?

if want use regex in code, need use re module.

so change line,

if ('\w*' + fname + '\w*') in files_list: 

to,

if re.search(r'\w*' + fname + r'\w*', files_list): 

which same as,

if fname in file_list: 

because \w* means 0 or more word characters. , think want use word boundaries.

if re.search(r'\b' + fname + r'\b', files_list):
