尝试查找最小值和最大值时，它仅适用于某些列表。以下是输出示例：
[[＆＃39; Amelia Cox＆＃39;，6,4,8,4,6]，[＆＃39; Georgina Cottrell＆＃39;，4,10,8,4,10]，[＆ ＃39; Isabella Jones＆＃39;，2,8,4,2,8]，[＆＃39; Jack Elsom＆＃39;，8,9,10,5,9]]
正如您所看到的，我的代码无法识别某些最小值和一些最大值。
这是我的代码：
def menu():
global user_password
if user_password == correct_password:
classes = input("Which class would you like to view? :")
classes = classes.lower()
while classes not in ["3a", "4a", "5a"]:
time.sleep(2)
classes = input("Input invalid. Please enter 3a, 4a or 5a: ")
if classes == ["3a", "4a", "5a"]:
break
if classes == "3a":
file = open("scores3a.csv", "r")
csv_f = csv.reader(file)
yourlists = list(csv_f)
file.close()
yourlists2 = [x for x in yourlists if x]
print("-------------------------------------------------------------\n"
"Welcome to the menu sytem to view your students scores.\n"
"-------------------------------------------------------------\n"
"Type the corresponding letter for what you would like to view:\n")
time.sleep(2)
all_scores = print("Input 'a' to see all of your students scores in alphabetical order(by forename)\n"
"and sorted into highest to lowest scores for each student")
time.sleep(2)
highest_scores = print("Input 'b' to see all of the students average scores\n"
"sorted into highest to lowest")
user = input()
if user == "a":
yourlists2.sort()
slices = yourlists2[0][:]
slices1 = yourlists2[1][:]
slices2 = yourlists2[2][:]
slices3 = yourlists2[3][:]
for row in slices:
slices[1]=int(slices[1])
slices[2]=int(slices[2])
slices[3]=int(slices[3])
lowest = min(slices[1:3])
slices.append(lowest)
highest = max(slices[1:3])
slices.append(highest)
break
for row in slices1:
slices1[1]=int(slices1[1])
slices1[2]=int(slices1[2])
slices1[3]=int(slices1[3])
lowest = min(slices1[1:3])
slices1.append(lowest)
highest = max(slices1[1:3])
slices1.append(highest)
break
for row in slices2:
slices2[1]=int(slices2[1])
slices2[2]=int(slices2[2])
slices2[3]=int(slices2[3])
lowest = min(slices2[1:3])
slices2.append(lowest)
highest = max(slices2[1:3])
slices2.append(highest)
break
for row in slices3:
slices3[1]=int(slices3[1])
slices3[2]=int(slices3[2])
slices3[3]=int(slices3[3])
lowest = min(slices3[1:3])
slices3.append(lowest)
highest = max(slices3[1:3])
slices3.append(highest)
break
yourlists2=[slices,slices1,slices2,slices3]
print(yourlists2)
menu()
如果有人可以提供帮助，我会非常感激。谢谢！ ：）
