custom data objects

It’s time to apply what you now know about Python’s dictionary to your code. Let’s continue to concentrate on Sarah’s data for now. Strike out the code that you no longer need and replace it with new code that uses a dictionary to hold and process Sarah’s data. 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) def get_coach_data(filename): try: with open(filename) as f: data = f.readline() return(data.strip().split(',')) except IOError as ioerr:

Strike out the code you no longer need.

print('File error: ' + str(ioerr)) return(None) sarah = get_coach_data('sarah2.txt') (sarah_name, sarah_dob) = sarah.pop(0), sarah.pop(0) print(sarah_name + "'s fastest times are: " +

Add your dictionary using and processing code here.

str(sorted(set([sanitize(t) for t in sarah]))[0:3]))
