Some code is attached below:

#Code of open filedefget_coach_data (filename):Try: with open (filename) as F:data=f.readline () temp= Data.strip (). Split (',')        return(athletelist (temp.pop (0), Temp.pop (0), temp)exceptIOError as E:Print('File Error:'+str (e))return(None)

# code with great style def top3 (self):     return  for  in self]) [0:3])

#demo of PickleImportPickleTry: With open ("Data.pickle",'WB') as Mysavedata:pickle.dump ([1, 2,'three'], Mysavedata)exceptPickle. Pickleerror as E:Print('File Error:'+ str (e))

# demo of Class class athletelist (list):     __init__ (Self, a_name, A_dob = None, a_times = []):         = a_name        = a_dob        self.extend (a_times)    def  top3 (self):         return for with self]) [0:3])
