hi i have my codes i have to do a module def subjects but i cant figure out how can u help me thanks.

class Enrol:

def init(self, dir):

def readFiles(, dir, files):

for file in files:

 if file == "classes.txt":
  class_list = readtable(dir+"/"+file)
  for item in class_list:
   Enrol.class_info_dict[item[0]] = item[1:]
   if item[1] in Enrol.classes_dict:
    Enrol.classes_dict[item[1]].append(item[0])
   else:
    Enrol.classes_dict[item[1]] = [item[0]]

 elif file == "subjects.txt":
  subject_list = readtable(dir+"/"+file)
  for item in subject_list:
   Enrol.subjects_dict[item[0]] = item[1]

 elif file == "venues.txt":
  venue_list = readtable(dir+"/"+file)
  for item in venue_list:
   Enrol.venues_dict[item[0]] = item[1:]

 elif file.endswith('.roll'):
  roll_list = readlines(dir+"/"+file)
  file = os.path.splitext(file)[0]
  Enrol.class_roll_dict[file] = roll_list
  for item in roll_list:
   if item in Enrol.enrolled_dict:
    Enrol.enrolled_dict[item].append(file)
   else:
    Enrol.enrolled_dict[item] = [file]

try: os.walk(dir, _readFiles, None)

except: print "directory not properly been recognise error"

def subjects(what should i write here??): for name in suject_list: print name,

out put should look like

import enrol

e = enrol.Enrol("/path/to/data")

e.subjects()

['bw101', 'bw110', 'bw232', 'bw290', 'bw660']
