In Python 3 5  os scandir is better if you need to check for file attributes or type - see os DirEntry for properties of the object that s returned by the function    import os   for file in os scandir path       if file name endswith   bak            os unlink file path    This also doesn t require changing directories since each DirEntry already includes the full path to the file

Via os listdir and os remove  import os  filelist     f for f in os listdir mydir  if f endswith  quot  bak quot     for f in filelist      os remove os path join mydir  f    Using only a single loop  for f in os listdir mydir       if not f endswith  quot  bak quot            continue     os remove os path join mydir  f    Or via glob glob  import glob  os  os path  filelist   glob glob os path join mydir   quot   bak quot    for f in filelist      os remove f   Be sure to be in the correct directory  eventually using os chdir

Use os chdir to change directory   Use glob glob to generate a list of file names which end it   bak   The elements of the list are just strings   Then you could use os unlink to remove the files   PS  os unlink and os remove are synonyms for the same function       usr bin env python import glob import os directory   path to dir  os chdir directory  files glob glob    bak   for filename in files      os unlink filename

I realize this is old  however  here would be how to do so using just the os module     def purgedir parent       for root  dirs  files in os walk parent                                                 for item in files                Delete subordinate files                                                              filespec   os path join root  item              if filespec endswith   bak                    os unlink filespec          for item in dirs                Recursively perform this operation for subordinate directories                purgedir os path join root  item

you can create a function  Add maxdepth as you like for traversing subdirectories   def findNremove path pattern maxdepth 1       cpath path count os sep      for r d f in os walk path           if r count os sep  - cpath  lt maxdepth              for files in f                  if files endswith pattern                       try                          print  Removing  s     os path join r files                            os remove os path join r files                       except Exception e                          print e                     else                          print   s removed     os path join r files    path os path join   home   dir1   dir2   findNremove path   bak
