Unix filename wildcards in Python?
Shell wildcard patterns don't work in Python. Use the fnmatch or glob modules to interpret the wildcards instead. fnmatch interprets wildcards and lets you match strings against them, glob uses fnmatch internally, together with os.listdir() to give you a list of matching filenames.
In this case, I'd use fnmatch.filter():
import osimport fnmatchfor dirpath, dirnames, files in os.walk(directory): for filename in fnmatch.filter(files, '*_ext'): fileNameToPickle = os.path.join(dirpath, filename) fileToPickle = pickle.load(open(fileNameToPickle, "rb"))If your structure contains only one level of subdirectories, you could also use a glob() pattern that expresses that; the */ in the path of expression is expanded to match all subdirectories:
import globimport osfor filename in glob.glob(os.path.join(directory, '*/*_ext')): # loops over matching filenames in all subdirectories of `directory`.
