title: Python error: TypeError: 'module' object is not callable for HeadFirst Python code
body: <p>I'm following the tutorial from the HeadFirst Python book. In chapter 7, I get an error message when trying to run the next code:</p>
  
  <p>Athlete class:</p>
  
  <pre><code>class AthleteList(list):
      def __init__(self, a_name, a_dob=None, a_times=[]):
          list.__init__([])
          self.name = a_name
          self.dob = a_dob
          self.extend(a_times)
  
      def top3(self):
          return(sorted(set([sanitize(t) for t in self]))[0:3])
  
  def get_coach_data(filename):
      try:
          with open(filename) as f:
              data = f.readline()
          templ = data.strip().split(',')
          return(AthleteList(templ.pop(0), templ.pop(0), templ))
      except IOError as ioerr:
          print('File error: ' + str(ioerr))
          return(None)
  
  def sanitize(time_string):
      if '-' in time_string:
          splitter = '-'
      elif ':' in time_string:
          splitter = ':'
      else:
          return(time_string)
      (mins, secs) = time_string.split(splitter)
      return(mins + '.' + secs)
  </code></pre>
  
  <p>and with the next module I do some tests:</p>
  
  <pre><code>import pickle
  
  import AthleteList
  
  def get_coach_data(filename):
      try:
          with open(filename) as f:
              data = f.readline()
          templ = data.strip().split(',')
          return(AthleteList(templ.pop(0), templ.pop(0), templ))
      except IOError as ioerr:
          print('File error (get_coach_data): ' + str(ioerr))
          return(None)
  
  def put_to_store(files_list):
      all_athletes = {}
      for each_file in files_list:
          ath = get_coach_data(each_file)
          all_athletes[ath.name] = ath
      try:
          with open('athletes.pickle', 'wb') as athf:
              pickle.dump(all_athletes, athf)
      except IOError as ioerr:
          print('File error (put_and_store): ' + str(ioerr))
      return(all_athletes)
  
  def get_from_store():
      all_athletes = {}
      try:
          with open('athletes.pickle', 'rb') as athf:
              all_athletes = pickle.load(athf)
      except IOError as ioerr:
          print('File error (get_from_store): ' + str(ioerr))
      return(all_athletes)
  
  
  print (dir())
  
  the_files = ['sarah.txt','james.txt','mikey.txt','julie.txt']
  data = put_to_store(the_files)
  
  data
  </code></pre>
  
  <p>This is the content of the Julie.txt file:</p>
  
  <pre><code>Julie Jones,2002-8-17,2.59,2.11,2:11,2:23,3-10,2-23,3:10,3.21,3-21,3.01,3.02,2:59
  </code></pre>
  
  <p>and it's almost the same with the other files</p>
  
  <p>I should get something like this output:</p>
  
  <pre><code>{'James Lee': ['2-34', '3:21', '2.34', '2.45', '3.01', '2:01', '2:01', '3:10', '2-22', '2-
  01', '2.01', '2:16'], 'Sarah Sweeney': ['2:58', '2.58', '2:39', '2-25', '2-55', '2:54', '2.18',
  '2:55', '2:55', '2:22', '2-21', '2.22'], 'Julie Jones': ['2.59', '2.11', '2:11', '2:23', '3-
  10', '2-23', '3:10', '3.21', '3-21', '3.01', '3.02', '2:59'], 'Mikey McManus': ['2:22', '3.01',
  '3:01', '3.02', '3:02', '3.02', '3:22', '2.49', '2:38', '2:40', '2.22', '2-31']}
  </code></pre>
  
  <p>but I get this error message:</p>
  
  <pre><code>['AthleteList', '__builtins__', '__cached__', '__doc__', '__file__', '__name__', '__package__', 'get_coach_data', 'get_from_store', 'pickle', 'put_to_store']
  Traceback (most recent call last):

      return(AthleteList(templ.pop(0), templ.pop(0), templ))
  TypeError: 'module' object is not callable
  </code></pre>
  
  <p>What am I doing wrong?</p>
