python - Always print multiple error lines -

-

i'm busy working on tool tagging documents. can't seem solve issue im having. see code below, these 2 functions small part of code:

def runsearch(): time.sleep(1) #checkt of de lengte van de list keywords groter dan 0, zo niet, moet je eerst keywords opgeven if len(keywords) > 0:     path_input = raw_input('give path check documents(e.g. /users/frank/desktop): ')     errcounter = 0      #hier word gekeken of de opgegeven directory bestaat     if os.path.isdir(path_input):         root, dirs, files in os.walk(path_input):             file in files:                 fullfile = os.path.join(root, file)                 if os.path.splitext(fullfile)[1].lower() == ('.docx') or \                                 os.path.splitext(file)[1].lower() == ('.doc') or \                                 os.path.splitext(file)[1].lower() ==  ('.pptx') or \                                 os.path.splitext(file)[1].lower() == ('.txt') or \                                 os.path.splitext(file)[1].lower() == ('.xlsx') or \                                 os.path.splitext(file)[1].lower() == ('.xls') or \                                 os.path.splitext(file)[1].lower() == ('.odt') or \                                 os.path.splitext(file)[1].lower() == ('.rtf') or \                                 os.path.splitext(file)[1].lower() == ('.csv') or \                                 os.path.splitext(file)[1].lower() == ('.html') or \                                 os.path.splitext(file)[1].lower() == ('.htm') or \                                 os.path.splitext(file)[1].lower() == ('.pdf'):                     tagdocs(fullfile)          print ('\nsearch keyword(s) completed.')         time.sleep(1)     else:         print("\nplease enter valid path, example: '/users/frank/documents'") else:     print('\nno keywords defined, use menu option 2 first.') raw_input("\npress enter continue...") menu()  def tagdocs(fullfile):     try:         content = textract.process(os.path.abspath(fullfile))         # contentlist.append(content)         words = content.split()         words = [words.lower() words in words]          tagcounter = 0          item in enumerate(words):             index, value in enumerate(keywords):                 if value in item:                     tagdocuments.append(fullfile)                     tagcounter += 1          if tagcounter != 0:             print ("\nin file '" + os.path.abspath(fullfile) + "' tag(s)" +  " found: " +                    str(tagcounter) + " time(s).")      except exception, e:         errorlog(e)         pass

every time there's error passed errorlog() print error 4 times in error.log. know what's causing this, it's because loops 4 times, because there 4 files, if add file folder im scanning, print error 5 times. question, how can make print error 1 time? prints error 1 time every file finds.

update #2

def errorlogonce(err):     if not err in reported_errors:         reported_errors.append(err)         errorlog(err)  def errorlog(e):     errcounter = 0     errcounter += 1      logging.basicconfig(filename='error.log',level=logging.debug)     logging.debug(e)

if want less lines of code, without classes, can this:

reported_errors = []  def errorlogonce(err):   if not err in reported_errors:     reported_errors.append(err)     errorlog(err)

and call errorlogonce instead of calling errorlog
