为什么我在使用pickle导入的def get_coach_data函数中出现语法错误，而当我删除pickle导入时却没有得到

Question

当我尝试运行此代码时，我在定义get_coach_data函数的行中收到语法错误。我试图在没有进口泡菜的情况下运行，而且效果很好。

import pickle

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)

class Athlete:
    def __init__(self, a_name, a_dob=None, a_times=[]):
        self.name = a_name
        self.dob = a_dob
        self.times = a_times

    def top3(self):
        return(sorted(set([sanitize(t) for t in self.times]))[0:3])



def get_coach_data(filename):
    try:
        with open(filename) as f:
            data = f.readline()
        templ = data.strip().split(',')
        return({'Name' : templ.pop(0),
                'DOB'  : templ.pop(0),
                'Times': str(sorted(set([sanitize(t) for t in                                                      templ]))[0:3])})
    except IOError as ioerr:
        print('File error: ' + str(ioerr))
        return(None)
