Keyword can't be an expression

[fcktheworld587]

In the following module, IDLE refuses to run it, siting "Keyword can't be an expression" and highlights the ( on the righthand side of AthleteList inside the get_coach_data function. What am I doing wrong? Edit: pycharm will run it with exit status 0

1	return(AthleteList(temp1.d=pop(0), temp1.pop(0), temp1))

the following is the full module

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34

import pickle from athletelist import AthleteList     def get_coach_data(filename):     try:         with open(filename) as f:             data = f.readline()             temp1 = data.strip().split(",")             return(AthleteList(temp1.d=pop(0), temp1.pop(0), temp1))     except Exception as ioerr:         print("File error:" + 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.picle', 'rb') as athf:                           all_athletes = pickle.load(athf)                 except IOError as ioerr:                       print('File error (get_from_store) ' + str(ioerr))                 return(all_athletes)

you forgot to post your AthleteList function.

Also this: temp1.d=pop(0). I'm not sure what that should be, maybe temp1.pop(0)?
