try:

    with open('James.txt') as jaf:

        data = jaf.readline()

        james = data.strip().split(',')



    with open('Julie.txt') as juf:

        data = juf.readline()

        julie = data.strip().split(',')



    with open('Mikey.txt') as mif:

        data = mif.readline()

        mikey = data.strip().split(',')



    with open('Sarah.txt') as saf:

        data = saf.readline()

        sarah = data.strip().split(',')

    

except IOError as err:

    print('File error: ' + str(err))



print(sorted(james))

print(sorted(julie))

print(sorted(mikey))

print(sorted(sarah))



clean_james = []

clean_julie = []

clean_mikey = []

clean_sarah = []



def sanitize(time_string):

    if '-' in time_string:

        splitter = '_'

    elif ':' in time_string:

        splitter = ':'

    else:

        return(time_string)

    (mins,secs) = time_string.split('-')



for each_t in james:

    clean_james.append(sanitize(each_t))

for each_t in julie:

    clean_julie.append(sanitize(each_t))

for each_t in mikey:

    clean_mikey.append(sanitize(each_t))

for each_t in sarah:

    clean_sarah.append(sanitize(each_t))



print(sorted(clean_james))

print(sorted(clean_julie))

print(sorted(clean_mikey))

print(sorted(clean_sarah))

Traceback (most recent call last):
File "F:\python\demo-file4.py", line 42, in <module>
clean_james.append(sanitize(each_t))
File "F:\python\demo-file4.py", line 39, in sanitize
(mins,secs) = time_string.split('-')
ValueError: not enough values to unpack (expected 2, got 1)

是这个错误求大神们指点迷津

time_string中间没有“-”符号吧，导致分割失败。

def sanitize(time_string):
    if '-' in time_string:
        splitter = '_'
    elif ':' in time_string:
        splitter = ':'
    else:
        return(time_string)
    (mins,secs) = time_string.split('-')

这段代码我猜应该是这么用的


  if '-' in time_string:
        splitter = '-'
    elif ':' in time_string:
        splitter = ':'
    else:
        return(time_string)
    (mins,secs) = time_string.split(splitter)

谢谢你是我太粗心了，现在那个问题解决了，现在又出现一个新问题 print(sorted(clean_james)) TypeError: unorderable types: NoneType() < NoneType() QAQ我没有见过这个错误，能帮忙解答下么
